Matlab table to matrix

Stumbled upon this question/answer while seeking how to compute the row sums of a matrix. I would just like to add that Matlab's SUM function actually has support for summing for a given dimension, i.e a standard matrix with two dimensions. So to calculate the column sums do: colsum = sum(M) % or sum(M, 1) and for the row sums, simply do
