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))

Arguments

: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.
