Hi Stephen, 

   

1. Make sure that the filename is correct. If your data file is
called xyz.dat then the first command should be fid = mopen(‘xyz.dat’,’r’)
or you do: filename  =  ‘xyz.dat’; fid =  mopen(filename,’r’); 

2. Make sure that the data file is in the current working directory
or make sure that the path is correct for example: fid = mopen(‘.../data/xyz.dat’,’r’). 

   

Cheers, 

   

Francis

  hi im a newuser to
  scilab..not much prior experience in any other equivalent software too 
  i want to open a file for reading a set of x y z values from scilab

   i copeied the code frm

   

 http://spiff.rit.edu/classes/phys317/lectures/readwrite.html

  

  Code

  

   fid = mopen(filename, "r");

  if (fid == -1)

    error("cannot open file for reading");

  end

  

to scipad editor and tried to execute via  "Load into scilab" i had created an empty file in home directory named "filename "via gedit

before execution .

While execution says "Undefined variable 'filename'

then i changed the code to 

   

fid = mopen("filename", "r");

  

ie added " " before and after filename then it executes..

what is the problem here i cant understand it...I just copied it as it is from

 http://spiff.rit.edu/classes/phys317/lectures/readwrite.html

Is the syntax used here is wrong??

Where should i get the correct syntax for the function mopen and other functions then?

  

i tried 'help mopen'

  and it displayed

  

Calling sequence

  

[fd.err]=mopen( file [,mode ,swap]) 

  

  Is this the proper syntax ?? I dont think so ,where should i get the corret sequence then?

 somebody please help..

Thanks
