WebWhile faster matrix multiplication algorithms exist asymptotically, in practice most such algorithms are infeasible for practical problems. In this note, we describe an alternate way to use the broken matrix multiplication algorithm to approximately compute matrix multiplication, either for real-valued matrices or Boolean matri-ces. WebNov 16, 2013 · Matrix multiplication is a series of multiply-and-add operations. If the inputs are all ones and zeros, the result of such an operation will be "zero or greater than zero". So setting every value >0 to 1 in the product will solve your issue. Example: booleanResult = (result > 0); Or booleanResult = logical (result);
