This appears to be a problem with the gpuArray version of dct. Thanks for reporting this.

Just installed 2022a, and get "Error using dct. Input gpuArray must be a vector or two-dimensional matrix." Any solution for this on the horizon?

Reshape your input to the same number of rows and [] columns. dct() that. Reshape back.
