opCurvelet
 opCurvelet  Two-dimensional curvelet operator.
 
    opCurvelet(M,N,NBSCALES,NBANGLES,TTYPE) creates a two-dimensional
    curvelet operator for M by N matrices. The curvelet transform is
    computed using the Curvelab code.
 
    The remaining three parameters are optional; NBSCALES gives the
    number of scales and is set to max(1,ceil(log2(min(M,N)) - 3)) by
    default, as suggested by Curvelab. NBANGLES gives the number of
    angles at the second coarsest level which must be a multiple of
    four with a minimum of 8. By default NBANGLES is set to 16. TTYPE
    determines the type of transformation and is set to 'WRAP' by
    default.
