M2SCI function

mtlb_setstr - Matlab setstr emulation function

### Description

Matlab `setstr` and Scilab `ascii` behave differently in some particular cases:

  - With character string input: Matlab `setstr` returns a character string while Scilab `ascii` returns ASCII codes.
  - With double matrix input: Matlab `setstr` returns a character matrix having the same size as input while Scilab `ascii` returns a single character string

The function `mtlb_setstr(A)` is used by `mfile2sci` to replace `setstr(A)` when it was not possible to know what was the input while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace `mtlb_setstr` calls:

  - If `A` is a character string or a character string matrix `mtlb_setstr(A)` may be replaced by `A`
  - If `A` is a double row vector `mtlb_setstr(A)` may be replaced by `ascii(A)`

Caution: `mtlb_setstr` has not to be used for hand coded functions.
