[Scilab-users] Logical zero

[Jan-Åge Langeland]

I ran a little speed test with the different alternatives, I found the 
results surprising:

//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
