Hello,

So I do have a function, which has the (same sized) vectors x,y,z as input parameters and a same sized k as an output parameter.

Now I want to calculate k with a simple for loop. As I come from other languages I could get it to run. However it is pretty slow and I know MATLAB has a lot of tricks for these kind of stuff.

So the minimal running example code is:

A=2.*p+1;

Bm=p+1;

Bs=p+2;

x_i=(x+y)*0.01;

x_s=x-x_i;

[r,c] = size(T);

k = zeros(r,c);

for i=1:r

if x(i)>=x_i(i)

k(i)=A(i)+Bm(i).*x_s(i);

elseif x(i)<x_i(i)

k(i) = A(i)+Bs(i).*x_s(i);

end

if k(i)==0

k(i) = 0.001;

end

end

Does MATLAB have a more efficient way to implement this?

Thanks in advance
