# nfreq

frequency of the values in a vector or matrix. This function is obsolete.

### Calling Sequence

`m=nfreq(x)`

### Arguments

x

real or complex vector or matrix

### Description

Frequency 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 frequencies of the corresponding values.

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

 This function is obsolete.
It is better to use tabul instead of `nfreq`.

### Examples

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

### See Also

• tabul — frequency of values of a matrix or vector
• dsearch — distribute, locate and count elements of a matrix or hypermatrix in given categories
• histplot — plot a histogram

### History

 Version Description 5.5.0 Function tagged as obsolete. Will be removed in 5.5.1. Please use tabul instead.
