A matrix and its transpose have the same eigenvalues. If A and B are two square matrices of the same order, then AB and BA have the same eigenvalues. The eigenvalues of an orthogonal matrix are 1 and -1. If λ is an eigenvalue of A, then kλ is an eigenvalue of kA, where 'k...

How do you find an elementary matrix? What is the standard matrix of a linear transformation? How to find pseudo-inverse of a matrix? Find the transpose of the matrix. [2 8 0 -1 7 2 -1 5] Find the matrix X such that A x B = I, where I is the 2 x 2 identity matrix and ...
% symmetrize the matrix, by adding it to its transpose, then reduce the diagonal M = M + M.' - diag(diag(M)); end That final line of code just adds the triangular matrix to its NON-conjugate transpose, which essentially doubles the diagonal elements. Then it subtracts off those diag...
In this code, you are creating a 3x3 array arr_1 storing the values from 1 through 9. Then, you create a 2x2 slice of the original array storing from the second value to the end in both dimensions, arr_2. Notice that the Python indexing is 0-based, so the second element has the...
All of them boil down what origin (0, 0, 0) are these coordinates currently relative to? Once you know that, you can then transform them, via some matrix, to some other vector space if need be. Typically, when the output of some shader looks wrong, it's because of some coordinate ...
It’s easier to integrate angular velocity using a quaternion than a 3x3 matrix Normalizing a quaternion is faster than orthonormalizing a 3x3 matrix It’s really easy to interpolate between two quaternions We’ll still use matrices but as a secondary quantity. This means that each frame after ...
