Using fft on a partially staggered grid

  1. Jun 2, 2015 #1
    Hi, I was wondering if anyone could give me a hand.

    I am wondering if it possible to use standard spectral methods to compute the derivative of a function on a partially staggered grid.

    e.g. from 0 to pi I would perform the differentiation on the nodes

    j*(pi/N) j=1,2,3 ..... N-1

    and from 0 to pi i would preform the differentiation on

    pi+(pi/2N)+(j-N)*(pi/N) j=N,...., 2N-1

    possibly a standard interpolation scheme would be sufficient but i was wondering if anyone had any better ideas

    thanks
