I have a matrix T = [T11, T12 ; T21, T22] of size , where all elements in T are 126*126. After using this function [Val, Vect] = eig(T); I obtained matrices of Val() , and Vect (digonal). Now I have eigenvactors and eigenvalues. I need to implem...
Learn about factor analysis - a simple way to condense the data in many variables into a just a few variables.
Consider A to be a square matrix of size n and S to be asymmetricsquare matrix of size n. I know the first row of A and I know each element in S. I need to find the remaining elements (from row 2 to row n) of A such that A'A = S. Thi...
The next step involves the construction andeigendecompositionof thecovariancematrixCx= (1/n)X'X(in case of z-scored data the covariance is equal to the correlation matrix since the standard deviation of all features is 1). Eigenvaluesare thensortedin adecreasingorder re...
In summary, the conversation discusses how the solution to the heat equation can be made up of a linear combination of solutions to similar equations, as long as the matrix formed by the coefficients of the equations has no zero eigenvalues. This is due to the linear ...
C++ you will input matrices and determine whether or not they are Magic Squares. A Magic Square is an n x n matrix (n is an odd integer >= 3) in which each of the integers 1, 2, 3 ..., n2 appears exa How to find the biggest decrease in an array in python?
