I would like to put another question about matrix operations... template <typename T> struct TMatrix
I\'m trying to generate a matrix by applying a function to all combinations of elements of two vectors -- something like this:
I have a matrix with diagonals equal to zero and off-diagonals all equal to one (the inverse of an identity matrix):
Input matrix A column1column2column3column4 row10100 row200-10 row3100-1 Input matrix B column5column6column7column8
I\'ve got a plain text data file (.dat) containing sparse matrix information that I\'d like to import into MATLAB.It looks a bit like:
I\'ve been working on a DIY linalg solver for a few days, and its coming together (no small things to you guys at stackexchange) But I\'m currently experiencing a Brain Fart and can\'t see what\'s wro
I feel a bit silly asking this, but I can\'t seem to find the answer Using arrays in Numpy I want to multiply a 3X1 array by 1X3 array and get a 3X3 array as a results, but because dot function alway
I have a Java program which will produce a large matrix, at the end I want to save that matrix to a DATABASE \'MYDATABASE\' in a myMatrixTable
I have a multidimensional array a with shape (nt, nz, ny, nx). The dimensions are time, z, y, x. For each time, x and y, I\'ve selected the appropriate z in a new index array J with shape (nt, ny, nx)
This bot开发者_开发技巧hers me a bit: Suppose you have a matrix with three layers. Is there a simple way to multiply this matrix with a vector of three elements so that the first layer (all elements
