Similar to CUMSUM but in this case each column is divided by an unity increasing weight.
For vectors it is equivalent to:
cumsum(x)./((1:length(x))')

The CUMMEAN(x,DIM) can be taken in any non-singleton dimension (DIM).

This function is useful to compare performance of an estimator with respect to the sample mean of a set of measurements.
