Running code for different variable values.

Lets say I have these values here.

theta = 0:2:12.

How do I get matlab to go through the code while the value is zero, get the data, then go through the code while the value is 2, and so on and so forth.

I have been using the for loop...

for i = 1:length(theta)
    code code code
    code code code
end

but it seems to run a line for all values, save that in an array, then do it for the next line. As a result im running into array incompatibility issues, because my code has 1 by 476 matrix inside of it as well. So I just want to know how yall would go through this.

For example, phi is a 1 by 476 matrix, so when I get to

alpha = theta - phi,

im getting an imcompatible size error. But I want theta to equal zero for the whole code, then I want matlab to come back and solve it while theta is 2, in a clean way.

theta = 0:2:12;
num_theta = length(theta);
alpha = zeros(num_theta, 147);
for i = 1 : num_theta
    this_theta = theta(i);
    code code code
    alpha(i, :) = this_theta - phi;
end
