colMean(a)

Array statistics - determines the Mean value of each column in an array

Syntax

o_colmean(a)

a: array 2D numeric - input 2D array

return: array 2D - statistics of each column

Usage

When analyzing plentiful data, such as with a number of tests on many DUTs it can be desirable to examine the statistics of various parameters. A typical way to represent the data is in an array, with each row representing a test vector, each column a particular tested parameter. This function analyzes the Mean value of each column- hence each parameter.
