WebApr 22, 2016 · \$\begingroup\$ My MATLAB's a bit rusty. I'm happy that as k is vector, k.^2 produces a k squared vector, but I'm not sure about the a., as a is a scalar. One way or another however, you've got to get the simple x=a_guassian right before you do the difficult bit of interpreting its FFT. WebDescription. Y = circshift (A,K) circularly shifts the elements in array A by K positions. If K is an integer, then circshift shifts along the first dimension of A whose size does not equal 1. If K is a vector of integers, then each element of K indicates the shift amount in the corresponding dimension of A.
