MIN∑

This operation gets the minimum values from 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. The operation calculates the minimum of each column of data in the real matrix and pushes the result into the stack.

If the real matrix has a single column, then a real value which is the minimum of all values in that column is pushed onto the stack. If the real matrix has two or more columns, then a real vector with the same number of columns is pushed onto the stack where each value in the vector is the minimum of values from that column.
