MATLAB: How to rearrange multiple results of a function without using for loop

Question

Hi there,

I created function Array(k) which produces an array of 1xN element for the input k.

N = 115824;
Array = linspace(1*k,k*N,N)

I want to apply that function to an array of k = 1:115824. I tried with for loop it but it's very slow.

for k = 1:N
    result(k,1:N) = Array(k);
end

Are there any other way to do this task faster and still give me the result as that for loop?

Thank you

Answer 1

Assuming that the initial value of k = 1, then it can be avoided using the

repmat

command as follows (see vector B),

N = 11;
k=1;
Array = linspace(1*k,k*N,N)';
for k=1:N
    result(k,1:N) = Array(k);
end
B = repmat(Array,[1 N])
