M2SCI function
mtlb_a - 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 by
mfile2sci
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
A
and
B
are character strings,
mtlb_a(A,B)
may be replaced by
asciimat(A)+asciimat(B)
-
If both
A
and
B
are not empty matrices
mtlb_a(A,B)
may be replaced by
A+B
,
else
mtlb_a(A,B)
may be replaced by
[]
.
-
If mtlb_mode==%T, then
mtlb_a(A,B)
may be replaced by
A+B
in any case where
A
and
B
are not character string matrices.
Caution:
mtlb_a
has not to be used for hand coded functions.
