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.
Examples
geomean(1:10) // Returns factorial(10)^(1/10) = 4.5287286881167648
