mtlb_i - Matlab insertion emulation function
Description
Matlab and Scilab insertion behave differently in some particular cases:
-
-
-
When inserting a matrix in a variable: Matlab automaticaly adjusts output
variable to fit with matrix to insert but not Scilab.
For example, with A=1, A([1,2,3,4])=[1,2;3,4]) returns an error in Scilab
while in Matlab we get A=[1,2,3,4]. If values miss comparing to indexes,
Matlab fills output value with 0.
-
When inserting data into 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), insertion in such a type of
matrix does not differ from other. But in Scilab it can't be done so...mtlb_is is an alternative.
The function A=mtlb_i(A,k,B) is used by
mfile2sci to replace A(k)=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_i calls:
-
-
-
If A is not a vector
A=mtlb_i(A,k,B) may be replaced by A(k)=B
-
If A and B are both row or column vectors
A=mtlb_i(A,k,B) may be replaced by A(k)=B
Caution: mtlb_i has not to be used for hand coded functions.
