This operation returns the number of samples in the statistics data. It expects to find a variable called ∑DAT which has a set of statistics values stored in a real matrix. Each row in the real matrix represents a single set of samples. Each column contains one of the set of values associated with a single sample. This operation pushes the number of rows in the ∑DAT real matrix onto the stack.
