strange - range

### Calling Sequence

  `[r]=strange(x)`
  `[r]=strange(x,'r') (or, equivalently, [r]=strange(x,1))`
  `[r]=strange(x,'c') (or, equivalently, [r]=strange(x,2))`

### Parameters

- `x` : real or complex vector or matrix

### Description

The range is the distance between the largest and smaller value, [r]=strange(x) computes the range of vector or matrix x.

[r]=strange(x,'r') (or equivalently [r]=strange(x,1)) give a row vector with the range of each column.

[r]=strange(x,'c') (or equivalently [r]=strange(x,2)) give a column vector with the range of each row.
