What is the fastest method for matrix multiplication of an Eigen::Matrix over a random set of column indices? Eigen::MatrixXd mat = Eigen::MatrixXd::Random(100,
I want to calculate the Determinant of a Singular Matrix (which has a 0 determinant) with Numpy and when I print the determinant it shows a really small number
If we want to search for the optimal parameters theta for a linear regression model by using the normal equation with: theta = inv(X^T * X) * X^T * y one step
If I have the upper triangular portion of a matrix, offset above the diagonal, stored as a linear array, how can the (i,j) indices of a matrix element be extrac
I've got coordinates of 4 points in 2D that form a rectangle and their coordinates after a perspective transformation has been applied. The perspective trans
