cJ()

function out=cJ(in)

Input:

• in: $N_s$ sets of $d=3$ dimensional data, stored as an $\prod S_k\,\times\,N_s$ matrix

Global variables:

• gbl_S: dimensions of $d=3$ dimensional data sets

Output:

• out: cJ operator applied to in

Generalize the software in your file ``cJ.m'' according to the above prototype by following the same procedure you used to generalize ``cI.m''.
