WebHere, the function fftshift () renders the array k monotonically increasing and changes Y_k accordingly. The pairs zip (k, Y_k) are not changed by applying this operation to both vectors. This changes appears to fix the issue: Y_k = fftshift (fft (ifftshift (Y))) k = fftshift (fftfreq (len (Y))) plotReIm (k,Y_k) WebSets each bit to 1 if only one of two bits is 1: x ^ y: Try it » ~ NOT: Inverts all the bits ~x: Try it » << Zero fill left shift: Shift left by pushing zeros in from the right and let the leftmost bits fall off: x << 2: Try it » >> Signed right shift: Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost ...

WebSep 29, 2008 · The &, and ^ operators in Python work just like in C. The ~ operator works as for a signed integer in C; that is, ~x computes -x-1. You have to be somewhat careful with left shifts, since Python integers aren't fixed-width. Use bit masks to obtain the low order bits. For example, to do the equivalent of shift of a 32-bit integer do (x << 5 ...
