A very common question among new MATLAB users is how to store the results of a calculation done in a for loop. I covered how to do this when the result is a scalar. However, I did not cover how to do this if you are creating a vector each time through the loop.
I often see people try to store the results in a series of vectors with names like alpha1, alpha2, alpha3... This is not a good idea, it is hard to manipulate and refer to these variables. Better is to store each resultant vector as a row in a larger matrix.
