# nfreq

frequence of the values in a vector or matrix

### Calling Sequence

m=nfreq(x)

### Arguments

- x
real or complex vector or matrix

### Description

Frequence of the values in a real or complex vector or a
real or complex matrix `x`

.

For a real or complex vector or a real or complex matrix
`x`

, `m=freq(x)`

returns in the first column of
the `size(x,'*')x2`

matrix `m`

the values of
`x`

and in the second column of this matrix the
frequences of the corresponding values.

Note that the tabul function is more efficient, applies
also to vector of strings and returns a sorted `m`

.

### Examples

x=[2 8 0 3 7 6 8 7 9 1] m=nfreq(x)
