Examples
x = [2 2 3 4 14]; // Mean absolute deviation of a set of data // Expected = (|2-5|+|2-5|+|3-5|+|4-5|+|14-5|) / 5 = 3.6 mad(x) |  |  |
mean absolute deviation
s2 = mad(x) s2 = mad(x, orientation)
real or complex vector or matrix
index of the dimension along which the mad is computed. It can be either
"*" (default), "r" or
"c"real or complex scalar or vector
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) or 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.
x = [2 2 3 4 14]; // Mean absolute deviation of a set of data // Expected = (|2-5|+|2-5|+|3-5|+|4-5|+|14-5|) / 5 = 3.6 mad(x) | | |
