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.
The determinant of a matrix is a numerical value that represents certain properties of the matrix. It is calculated using a specific formula and can be used to solve systems of linear equations, find the area of a parallelogram or volume of a parallelepiped, and determine...
The inverse of a NxN matrix only exists only if the matrix has rank N. In other words, the linear operator that the matrix represents is surjective. Computing the inverse in a computer has numerical subtleties. That warning is telling you that the matrix is rank deficient. ...

What is the determinant of the matrix? {eq}\left[4\right] {/eq} Determinant of a Matrix: In order to determine whether or not we can find the inverse of a matrix, we need to compute its determinant. This is a single number, and its formula is different depending on the size of th...
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...
What is the inverse of \begin{bmatrix} -4 & 15 & -8\\ -1 & 4 & -2\\ -1 & 8 & -1 \end{bmatrix}? To move the 3, the inverse operation is subtraction. Then, to move the 5, the inverse operation is multiplication. Then, to move the 2, the inverse operation is division....
