geomean

geomean — geometric mean

Calling sequence

gm=geomean(x)  
gm=geomean(x,'r')(or,  equivalently,   gm=geomean(x,1))  
gm=geomean(x,'c')(or,   equivalently,  gm=geomean(x,2))

Parameters

`x`	:real or complex vector or matrix

Description

This function computes the geometric mean of a vector or matrix x . For a vector or matrix x , gm=geomean(x) returns in scalar gm the geometric mean of all the entries of x .

gm=geomean(x,'r') (or, equivalently, gm=gmean(x,1) ) returns in each entry of the row vector gm the geometric mean of each column of x.

gm=geomean(x,'c') (or, equivalently, gm=gmean(x,2) ) returns in each entry of the column vector gm the geometric mean of each row of x.
