mtlb_fftshift
Matlab fftshift emulation function
Description
Matlab and Scilab fftshift
behave differently in some particular cases:
With character string input: due to the fact that character strings are not considered in the same way in Matlab and Scilab, results can be different for this kind of input.
With two inputs: Matlab
fftshift
can work even ifdim
parameter is greater than number of dimensions of first input.
The function mtlb_fftshift(A[,dim])
is used by
mfile2sci
to replace fftshift(A[,dim])
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_fftshift
calls:
If
A
is not a character string matrix,mtlb_fftshift(A)
may be replaced byfftshift(A)
If
A
is not a character string matrix anddim
is not greater thansize(size(a),"*")
,mtlb_fftshift(A,dim)
may be replaced byfftshift(A,dim)
Caution: mtlb_fftshift has not to be used for hand coded functions. |
