mtlb_conv - Matlab conv emulation function

### Description

Matlab `conv` and Scilab `convol` behave differently in some particular cases:

  - With column vector inputs: if at least input is a column vector Matlab `conv` returns a column vector but Scilab `convol` always returns a row vector.

The function `mtlb_conv(u,v)` is used by `mfile2sci` to replace `conv(u,v)` when it was not possible to know what were the inputs 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_conv` calls:

  - If `u` and `v` are row vectors, `mtlb_conv(u,v)` may be replaced by `convol(u,v)`
  - If `u` or `v` is a column vector, `mtlb_conv(u,v)` may be replaced by `convol(u,v).'`
  - If `u` and `v` are column vectors, `mtlb_conv(u,v)` may be replaced by `convol(u,v).'`

Scilab `convol` sometimes returns values that may be rounded using `clean` to have a closer result from Matlab one.

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