Hi everybody,

I want to convert a logical array to any type of nuemeric array.
But I do not know how.
Any help is appreciated

A = rand(5) % a double array
LA = A < .5 % a logical array
DLA = double(LA) % logical array turned into a double array

Dear Amal!

Another idea:
help cast

well...

v=false(1,100000);
tic;
for i=1:1000
vd=double(v);
end
t1=toc;
tic;
for i=1:1000
vd=cast(v,'double');
end
t2=toc;
% wintel sys: i2c/2*2.6ghz/2gb/winxp.sp3.32/r2009b
disp([t1;t2]);
%{
0.20388 % <- DOUBLE
0.73422 % <- CAST
%}

....just a thought, as usual...
