BTY, I am worried about the Scilab 6.0 timing (3.3228213 seconds) of
a(1:n,1:m)=%f;
i.e. more than ten times slower than Scilab 5.5.1 (0.2964019 seconds).
Does somebody have an explanation ?

I ran a little speed test with the different alternatives, I found the
results surprising:
Jan
//script ftest.sce m=10000 n=10000 v=ver(); disp(v(1,1:2)); clear a;
timer(); a = zeros(n, m) == 1; //best in Scilab 6.0.0 disp(timer());
clear a; timer(); a=zeros(n,m)>0; disp(timer()); clear a; timer();
a=%f(ones(n,m)); disp(timer()); clear a; timer();
*a**(**1**:**n**,**1**:**m**)**=**%f**;* //best in Scilab 5.5.1
disp(timer()); clear a; //end script ftest.sce -->exec('ftest.sce',-1)
