mad

mean absolute deviation

Calling Sequence

s2=mad(x)
s2=mad(x,'r') or s2=mad(x,1)
s2=mad(x,'c') or s2=mad(x,2)

Arguments

x

real or complex vector or matrix

Description

This function computes the mean absolute deviation of a real or complex vector or matrix x.

For a vector or matrix x, s2=mad(x) returns in scalar s2 the mean absolute deviation of all the entries of x.

s2=mad(x,'r') (or, equivalently, s2=mad(x,1)) returns in each entry of the column vector s2 the mean absolute deviation of each column of x.

s2=mad(x,'c') (or, equivalently, s2=mad(x,2)) returns in each entry of the column vector s2 the mean absolute deviation of each row of x.
