Problem 44322. Make one vector from two others

You are given two vectors of equal length. Your task is to create a MATLAB script that will repeat all of the values in the first matrix a number of times equal to the corresponding place in the second matrix. For example:

M1=[1 3 5 7] and M2=[2 4 0 6]

You will want to have your output vector be two ones, four threes, zero fives and six sevens, or [1 1 3 3 3 3 7 7 7 7 7 7] You can assume that all of the values in M2 are greater than or equal to zero.

While this can be done with a for loop and repmat, I'm hoping that the brilliant minds here in Cody can come up with a better way to do this!
