Hi, I have data with dimension 1x25, where
x = rand(1,25);
D = size(x,2);
I'm trying using this code, but the result is NaN. Please help me, to fix my code. Thanks
for col = 1: D
x(:,col)=double(x(:,col)-mean(x(:,col)));
end
for col = 1: D
x(:,col)=double(x(:,col)/std(x(:,col)));
end

x = rand(1,25);
x = (x-mean(x))/std(x)

Which Matlab release do you use? In 2018b the result is a 220x1 vector.
