# 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')
