bbpermute Create a permuting blackbox operator. [BB,DIM2]=bbredim(DIM1,order) creates an M-by-M black-box operator that rearranges the dimensions of a hypercube represented as a column vector. The elements of order must be a rearrangement of the numbers from 1 to length(DIM1). For images (i.e. 2D "hypercube"), bbpermute is either the identity operator or acts as the transpose operator. The adjoint operator, i.e. BB', is the inverse of BB. Therefore there is no need for a separate inverse. See also , , bbflipdim.
