As part of a computer application, a sub-routine needs to be written, whose input parameter has to be used in the computation ѝ where is a 100×100 symmetric, positive-definite matrix Note that is a fixed matrix, and it is only which is the input parameter. What is the most efficient way you can come up with to perform the required computation, if the sub-routine is called millions of times for arbitrary values of Your solution needs to be efficient in terms of both time and space taken by the algorithm.
