bbmult Multiply a black-box operator with a matrix. A black-box operator is a set of functions that computes matrix-vector products. The operator is only accessed this way. Normally, operations with a black-box operator returns a new black-box operator. You can use bbmult to get a full result. This function is not intended for evaluation of many products, such as iterative routines. Please see bbfunc or bbfuncm for handling this case. See also blackbox, bbfunc, bbfuncm, .
