mtlb_double - Matlab double emulation function

### Description

Matlab and Scilab `double` behave differently in some particular cases:

  - With character string input: Scilab `double` does not work with this type of input while Matlab `double` returns a matrix of ASCII codes.
  - With boolean input: Scilab `double` does not work with this type of input while Matlab `double` returns a matrix of double values.

The function `mtlb_double(A)` is used by `mfile2sci` to replace `double(A)` when it was not possible to know what were theinput 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_double` calls:

  - If `A` is a character string, `mtlb_double(A)` may be replaced by `asciimat(A)`
  - If `A` is a boolean matrix, `mtlb_double(A)` may be replaced by `bool2s(A)`
  - If `A` is a double matrix, `mtlb_double(A)` may be replaced by `A`

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