The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.
Does a matrix have to be square to be invertible? For an invertible matrix A if A^ {-1} = A^T, prove that det (A) = +1 and -1. what is the inverse of the following matrix, A? A=\begin{bmatrix} 1 & 0\\ 0& 1\end{bmatrix} What is the inverse of the following matrix...
What is the inverse of a transformation matrix? What is a badly conditioned matrix? What is an orthogonal transformation? What is orthogonal transformation? Determine if the matrix A = \begin{bmatrix} 1/2 & 0 & 0 & 1/2\\ 0 & 1/2 & 1/2 & 0 \\ 0 & 1/2 & 1/2 & 0\\ 1...
When an identity matrix (I) is multiplied with a matrix (A) of the same order, the product is the same matrix (A). i.e., AI = IA = A. So is the name (with respect to multiplication). What is the Inverse of Identity Matrix? The inverse of an identity matrix is itself. Because...

use a finite number of bits to represent any number (in MATLAB's case, 64 bits are used), if a matrix has very small numbers then some precision is lost because the computer has difficulty representing the numbers accurately. When you try to find the inverse...
Learn what nodal analysis is with helpful examples, why it's important, and the six steps used to perform a nodal analysis.
, which is the inverse of the matrix , so that if we multiplied both sides of the equation (on the left) by we’d get The applications of matrices reach far beyond this simple problem, but for now we’ll use this as our motivation. Let’s get back to understanding what matrices are...
