mtlb_e
Matlab extraction emulation function
Description
Matlab and Scilab extraction behave differently in some particular
cases:
- When extracting data from a matrix with a vector as index: Matlab
returns a row vector and Scilab returns a column vector.
- When extracting data from a character string matrix: due to the fact
that character string matrices in Matlab can be adressed as any other
matrix (each character can be adressed), extraction in such a type of
matrix does not differ from other. But in Scilab it can’t be done so
and part function has to be used.
The function mtlb_e(B,k) is used by mfile2sci to replace A=B(k)
when it was not possible to know what were the operands 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_e calls:
- If B is a vector A=mtlb_e(B,k) may be replaced by A=B(k)
- If B is a matrix A=mtlb_e(B,k) may be replaced by A=B(k).’
- If B is a character string matrix and k is a scalar or a vector
A=mtlb_e(B,k) may be replaced by A=part(B,k)
Caution: mtlb_e has not to be used for hand coded functions.
