Matlab fft emulation function
Matlab and Scilab fft
behave differently in some particular cases:
With one input parameter: If input is a scalar or vector Scilab equivalent for Matlab fft
is fft(...,-1)
else if input is a matrix Scilab equivalent for Matlab fft
is fft(...,-1,2,1)
The function mtlb_fft(X[,n,[job]])
is used by
mfile2sci
to replace fft(X[,n,[job]])
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_fft
calls:
If X
is a scalar or a vector
mtlb_fft(X,-1)
may be replaced by fft(X,-1)
If X
is a matrix
mtlb_fft(X,-1)
may be replaced by fft(X,-1,2,1)
