Re: loading data

[Jonathan C. Webster]

Try this.
I only asked for the third row out of four matrixs, but you get the idea.
ie Construct a command string in your 'for' loop and then eval it.

octave:21> str = sprintf('[');
octave:22> for i = 1:4
> str = strcat(str,  sprintf('a%d(3,:);',i));
> endfor
octave:23> str = strcat(str,']');
octave:24> str
str = [a1(3,:);a2(3,:);a3(3,:);a4(3,:);]
octave:25> qq = eval(str)

Good luck,

Jonathan
