mtlb_ifft

Matlab ifft emulation function

Description

Matlab ifft and Scilab fft behave differently in some particular cases:

  • With one input parameter: If input is a scalar or vector Scilab equivalent for Matlab ifft(A) is fft(A,1) else if input is a matrix Scilab equivalent for Matlab fft is fft(A,1,2,1)

The function mtlb_ifft(X[,n,[job]]) is used by mfile2sci to replace ifft(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_ifft calls:

  • If X is a scalar or a vector mtlb_ifft(X,1) may be replaced by fft(X,1)

  • If X is a matrix mtlb_ifft(X,1) may be replaced by fft(X,1,2,1)

Caution: mtlb_ifft has not to be used for hand coded functions.
