Matlab addition emulation function
Description
Matlab and Scilab addition behave differently in some particular cases:
- With character string operands: The
+operator is used into Scilab to catenate character strings, while Matlab realizes the sum of the operands ASCII codes. - With empty matrix: In Scilab, if one of the operands is an empty matrix the result of the addition is the other operand. In Matlab if one of the operand is an empty matrix the result of the addition should be an error or an empty matrix.
The function mtlb_a(A,B) is used bymfile2sci to replace A+B 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_a calls:
- If
AandBare character strings,mtlb_a(A,B)may be replaced byasciimat(A)+asciimat(B) - If both
AandBare not empty matricesmtlb_a(A,B)may be replaced byA+B, elsemtlb_a(A,B)may be replaced by[]. - If mtlb_mode==%T, then
mtlb_a(A,B)may be replaced byA+Bin any case whereAandBare not character string matrices.
Caution: mtlb_a has not to be used for hand coded functions.
