Example is propably from Matlab, but I want to do this in Scilab. I need fulfilment (which, as I think, isn't available in "conventional" contour2d) and a scale on the right. Have you any suggestions? Examples? Instructions? greetings, Piotr -- Piotr Kowalczewski tel.:506-170-113 GG: 3984915 http://lodzgame.pl <- ju? jest!!! http://pkow.pl From whalesuit at gmail.com Sat Jan 3 15:32:00 2009 From: whalesuit at gmail.com (Eric E) Date: Sat, 3 Jan 2009 09:32:00 -0500 Subject: Mac OS 10.5 Compilation issue Message-ID: <7426fe270901030632s6ca996far5c5b0a3f9285976c@mail.gmail.com> Hi, I'm trying to follow the instructions here: http://wiki.scilab.org/Compiling_Scilab_5.x_under_MacOSX to compile Scilab for Mac OS 10.5.

I have fixed permanently this issue in the master but I haven't merge the master with the macosx-branch recently. The workaround here is to add --disable-static to the configure options.

Is there anything similar? Well, depends what you mean by "tests of the build", if you want to check the creation of the binary itself, "make macros" is calling Scilab to build our macros. If you want to test Scilab features, "make check" is your friend. > + Also, when I do make install, I get an error back > from /usr/bin/install complaining about the -D option, which evidently > isn't supported by the Mac version of install.

If so, any > hints where should I look to change the -D to a -d? Pretty weird issue. What is your version of "install" ? (install --version) Can you copy/paste the 10 last lines and the error message that you get ? In the root directory of the source tree, what is the result of $ grep -E "(^INSTALL =|^INSTALL_DATA =)" Makefile ? Under Linux, I get: INSTALL = /usr/bin/install -c INSTALL_DATA = ${INSTALL} -m 644 The -D option is provided by the autotools (ie, I am not touching this flag ... yet) Sylvestre From whalesuit at gmail.com Mon Jan 5 00:19:47 2009 From: whalesuit at gmail.com (Eric E) Date: Sun, 4 Jan 2009 18:19:47 -0500 Subject: [scilab-Users] Mac OS 10.5 Compilation issue In-Reply-To: <1231102950.4463.33.camel@zlarin> References: <7426fe270901030632s6ca996far5c5b0a3f9285976c@mail.gmail.com> <1231040641.4402.154.camel@zlarin> <7426fe270901041252u48e40d3cua51645b3b6ddb9c1@mail.gmail.com> <1231102950.4463.33.camel@zlarin> Message-ID: <7426fe270901041519m714d33aara294eeecb43f8094@mail.gmail.com> > Well, depends what you mean by "tests of the build", if you want to > check the creation of the binary itself, "make macros" is calling Scilab > to build our macros. > If you want to test Scilab features, "make check" is your friend. Thanks, that does the trick. I just kicked off "make check", and I'm getting a lot of messages saying, e.g.: 315/1152 - [fileio] dir..........................................failed : error_output not empty Is this standard, or should I look into the outputs of make check? > Pretty weird issue. Yeah, the install issue does seem weird. > What is your version of "install" ? > (install --version) Install doesn't have a --version flag on mac, and I can't find it with strings /usr/bin/install either.

The output are probably just warnings. Try to run Scilab like ./bin/scilab -nw.

I think that Scilab is a magnificent program, but sometimes it is a little difficult to find help on specific matters, especially concerning graphics... I am using 4.1.2 trying to get decent looking plots. Can anyone tell me how to avoid very long y_tick marks in an axes with a much larger width than height? I would like to have the same length of y_tick marks as of x_tick marks (you can fix that in Matlab). They also make the position of the y_label to close to the y_tick.labels.

I'm looking for good GUI designer for scilab 5.x. Does it exist? According to the following quote it's at least planned: http://www.scilab.org/developers/index_developers.php?page=roadmap_family5 Scilab GUI generator To provide, via a dedicated editor, a GUI development environment to define easily custom interface (buttons, menus, listboxes, etc.) and generate automatically equivalent Scilab code. 2. I don't know is it worth to use SciGui module, but I've tried to install it into Scilab 5.0.3, although installation passed with out errors, but it fails on loading by totally braking Scilab. 3. Why does new docking header occupy figure space? IMHO, it isn't obvious behaviour and it confuses users. Moreover I have to rewrite old GUI applications due to this change. Is it final behaviour or you're planning to change it? Thanks.

Necesito calcular las ra?ces de ese polinomio para cada temperatura y como es de tercer orden debo tomar s?lo la ra?z real. Con esto quiero formar una tabla con todas las ra?ces reales para cada temperatura que considere. He hecho varios intentos, s? como hacerlo para un solo polinomio, pero quiero generar una tabla autom?ticamente. Agradezco cualquier consejo. -------------- next part -------------- An HTML attachment was scrubbed...

Yep. Under Linux, try: scilab -nw -f yourscript.sci or scilab -nw -e "plot3d()" (if you don't need graphic features, I recommand the option -nwni which is faster). > Sorry if this is not the right place for posting a question. > if it is, can you please direct me to the appropriate place? It is ;) Sylvestre From esmamian at gmail.com Wed Jan 21 02:39:50 2009 From: esmamian at gmail.com (esmamian) Date: Tue, 20 Jan 2009 20:39:50 -0500 Subject: %eps value can be different than 2.220D-16 Message-ID: <7e1354bc0901201739j70508e2ah55e64a60878569f9@mail.gmail.com> Hi All ! According to the scilab help, the %eps value is a constrain that represent the machine precision, so i thought it was different between 32 bits machines and the 64 bits ones, but no :-s I have Scilab 4.0.1 on a 32bits Windows machine and the %eps is 2.220D-16 My surprise was when i mounted Scilab 5.0.3 over a 64 bits Ubuntu 8.10 machine and got the same result :-? Anyone knows why %eps is the same and how i can compute an algorithm with more precision?

I hope it's the right place to post suggestions. 1) Is it possible to add support two element vector-row [rows columns] as input argument for function ones, zeros, eye? 2) Why does Scilab have function like mtlb_eig, although there is no eig function by itself? I understand it makes sense when there are both versions, but if there is the only one. What about providing aliases for such functions? Or you think that users have to do it themselves (eig = mtlb_eig)... 3) Scilab 5.x supports pasting multiline code from clipboard without executing? But is there key to make a new line manually, but not to execute the command in the console (Matlab has Shift+Enter)?

This has nothing to do with the 32/64 bits of the machine, which refer to the way the memory is addressed. See the wikipedia page for more details : http://en.wikipedia.org/wiki/64-bit#32_vs_64_bit Note that this is a good thing for Scilab users, since it guarantees that the results are the same, whatever the platform used. Furthermore, since Scilab 5., the double precision is used whatever the OS used : http://www.scilab.org/changes_5/#numerical_precision "Numerical precision of Scilab under Linux 32 bits has been switched to double precision (53 bits). Therefore, the precision on some specific computations is improved and the consistency between Microsoft Windows & GNU/Linux enhanced. " The following is, by the way, a short algorithm to compute eps. In Scilab, this algorithm is performed by the routine DLAMCH, from Lapack. The algorithm requires 53 iterations to perform, because this is the number of bits (+1) which are required to store the fractionnal part of a double precision floating point number (i.e. the size of the mantissa). eps = 1.0; done = 0; i = 0; while done==0 eps = eps / 2.0; if (1.0+eps==1.0) then done = 1; end i = i + 1; end eps = eps * 2; mprintf("i=%d", i); mprintf("eps=%e", eps); The reference for this is the paper by Malcom : "Algorithms to Reveal Properties of Floating-Point Arithmetic" Michael A.
