I have time series of matrices (e.g., ser[symm] and ser[rec]) for which I take the sum. I currently use a do loop over time to compute the sums needed. Is there a command or function available to do this (compute the sums of the the time series of matrices) faster? Thanks much.

I'm not sure whether you're summing over time, element by element, or summing over the elements at a given time period.

I need to take the sum over time of the time series of the matrices in question, to get a matrix of the same shape.

You can loop over the dimensions and use SSTATS to compute the sum over time, but that's probably no quicker.

Ok, thanks
