So im working in matlab and having a real problem trying to understand how strings work in matlab. When the result of an operation with accumarray leads to a large output array with low density of nonzero elements, you can save storage space by storing the output as a sparse matrix use the issparse input of accumarray to return a sparse matrix. This matrix is then multiplied with c to arrive at the 500by2 result. This matlab function returns a with its columns flipped in the leftright direction that is, about a vertical axis. The sizes of a and b must be the same or be compatible if the sizes of a and b are compatible, then the two arrays implicitly expand to match each other.
