bbcountreset Reset all counters in a black-box operator. If you have created a black-box operator with bbcount you may wish to reset all counters to zero. This is accomplished by bbcount. All counters will be reset, not just the top-counter. Example: this example reveals how many multiplications bbtauest performs, and show that a Kronecker product requires each sub-operator to be applied a large number of times. >> bb=bbcount(bbkron(bbcount(rand(10)),rand(50))); >> tau=bbtauest(bb); >> bb bb = counter 500x500 (Calls: 30, Mat-vec. products: 30) > kron 500x500 > counter 10x10 (Calls: 30, Mat-vec. products: 1500) | > matrix 10x10 > matrix 50x50 We can now reset the counter. >> bbcountreset(bb); bb bb = counter 500x500 > kron 500x500 > counter 10x10 | > matrix 10x10 > matrix 50x50 See also bbcount.
