thrownan - eliminates nan values

### Calling Sequence

  `[nonan,numb]=thrownan(x)`

### Parameters

- `x`: real or complex vector or matrix

### Description

This function returns in vector `nonan` the values (ignoring the NANs) of a vector or matrix `x` and in the corresponding places of vector `numb` the indexes of the value.

For a vector or matrix `x`, `[nonan,numb]=thrownan(x)` considers `x`, whatever his dimensions are, like a vector (columns first).

In Labostat, NAN values stand for missing values in tables.

### Examples

    x=[0.2113249 %nan 0.6653811;0.7560439 0.3303271 0.6283918]
