WebWe are using templates and typdefs to make Vec be the name of a vector class with vector components made from doubles. And we are defining Mat to be a vector the components of which are themselves doube-precision vectors. That is to say, we are treating the matrix as a list of its row vectors, and we think of the list as a kind of generalized vector. Web1 Answer. Gaussian elimination requires O ( n 3) operations, not O ( n 2). In general, matrix inversion has the same exponent as matrix multiplication (any matrix multiplication algorithm faster than O ( n 3) gives a matrix inversion algorithm faster than O ( n 3) ), see for example P.Burgisser, M.Clausen, M.A.Shokrollahi "Algebraic complexity ...
