WebThis technique is called memoization. Memoization speeds up the execution of expensive recursive functions by storing previously calculated results in a cache. This way, when the same input occurs again, the function just has to look up the corresponding result and return it without having to run the computation again. WebDriven by the above concerns, we have devised a practical and user-friendly sparse matrix class for the C++ language [31]. The sparse matrix class uses a hybrid storage framework, which
