meanc

Purpose

Computes the mean of every column of a matrix.

Format

y = meanc(x)
Parameters:x (NxK matrix) – data
Returns:y (Kx1 matrix) – contains the mean of every column of x.

Examples

x = meanc(rndu(1e5, 4));

After the code above, x is equal to:

0.5007
0.5004
0.4995
0.5016

In this example, 4 columns of uniform random numbers are generated in a matrix, and the mean is computed for each column. Due to the use of random input data in this example, your results may differ slightly.
