Can someone please help me solve for the coefficients (alpha) that minimize the following function?
error = 0 == sum((A-alpha*B).^2);
A = size 1 x 1300 [ 2 45 7 8 3 2 56 ...]
alpha = coefficients of size 1 x n
B = size n x 1300
I am not sure how to write the code and what functions to use. Any help is appreciated!

I am guessing that your system is linear.
If so, you can calculate the (1xn) vector of ‘alpha’ coefficients as:
alpha = A/B;
See the documentation on mrdivide,/ (link) for a full discussion.

Thank you! Didn't realize it was that easy.
