A step-by-step explanation of finding the inverse of a matrix using Gauss-Jordan Elimination. Up to 5x5 matrix.
5x5 [ ] Select method used:AdjointReduced Row Echelon More about this Invertible Matrix Calculator with steps The concept of inverse of matrix will appear in so many contexts in Algebra. First, for matrices, the idea is to be able to operate them in a similar manner as we would do with...
Let a and b be fixed constants and t be a variable. For which values of t is the matrix A = [1 1 1 ] [a b t ] [a^2 b^2 t^2 ] is invertible. Also prove that there is no real 5x5 matrix such that (A^2)+I=0 I don't even know where to begin this two problems...
Extreme matrixThe symmetric nonnegative inverse eigenvalue problem (SNIEP) asks when a list σ=( λ 1, λ 2,…, λ n) of n real numbers is the spectrum of an n× n symmetric nonnegative matrix. This problem is completely solved only for n4. Our main goal here is to contribute to ...
