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)

Arguments

:? :

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.

Examples

x=[0.2113249 0.0002211 0.6653811;0.7560439 0.3303271 0.6283918]
m=meanf(x,`rand`_(x))
m=meanf(x,[10 10 10;1 1 1],'r')
m=meanf(x,[10 10 10;1 1 1],'c')
