[scilab-Users] in16 matrix

[Francis Drossaert]

No, Scilab can't plot so much data; even though I have 8GB memory (Scilab is not particularly memory efficient). In my case it would not make much sense either. I need to use Boolean masks to pick out the data point belonging to certain sequences and sensor numbers.

I guess I could use double(data) as input. Probably it will save some memory but I doubt that it will speed up things.

Are you plotting or using all the data at once? I use double(data(index)) as input of part of data to functions that cannot handle integer type matrices. E.g. I don't plot all my data at once.

If someone has another solution I would also appreciate to get it!

Although plot2d(y) seems to work, it seems that there are Scilab function which can't handle integer matrices. Is there a work-around? I typically work with vectors with 2e7 elements which 1.6e8 bytes so some memory savings would be welcome.
