fftshift (Matlab function)

Shift zero-frequency component of discrete Fourier transform to center of spectrum

Matlab/Scilab equivalent

Matlab Scilab

Particular cases


Due to the fact that strings or not considered in the same way in Matlab and in Scilab, results are not equal if A is a string matrix or vector in fftshift(A) or fftshift(A,dim). mtlb_fftshift can emulate this particularity in Scilab.


In Matlab, dim can be greater than the number of dimensions of A but in Scilab you get an error message in this case. mtlb_fftshift can emulate this particularity in Scilab.


Matlab Scilab
Y = fftshift('str')
Y = 'rst'
Y = fftshift("str")
Y = "str"
Y = mtlb_fftshift("str")
Y = "rst"
