meanf - weighted mean of a vector or a matrix

Calling Sequence

m=meanf(val,fre)
m=meanf(val,fre,'r') or m=meanf(val,fre,1)
m=meanf(val,fre,'c') or m=meanf(val,fre,2)

Parameters

Description

This function computes the mean of a vector or matrix x . For a vector or matrix x , m=mn(x) returns in scalar m the mean of all the entries of x . m=mn(x,'r') (or, equivalently, m=mn(x,1) ) returns in each entry of the row vector m the mean of each column of x . m=mn(x,'c') (or, equivalently, m=mn(x,2) ) returns in each entry of the column vector m the mean of each row of x .
