There is something really wrong here then. I executed the following
MATLAB code:
x1=rand(25000,1);
x2=rand(25000,1);
...
x11=rand(25000,1);
save foo -v4 x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11
and then loaded 'foo.mat' using io.loadmat in a fraction of a second. I
was using MATLAB version 7, hence the -v4 switch to get lowest common
denominator MATLAB file.
