How to find elementary matrix
To explain how matrix multiplication comes into play, let us write R(−) for a particular row operation on m × n matrices, so that the given operation is represented by A ↦ R(A) . It turns out that for any of the three types of row operations we have considered above, one has the identity. R(A) = R(I ∗ A) =R(I) ∗ A. Now using these operations we can modify a matrix and find its inverse. The steps involved are: Step 1: Create an identity matrix of n x n. Step 2: Perform row or column operations on the original matrix (A) to make it equivalent to the identity matrix. Step 3: Perform similar operations on the identity matrix too.

Given $$X = \begin {bmatrix} 0 & 1\\ -2 & -18\end {bmatrix}$$ find elementary matrices $E_1$, $E_2$ and …rank (a) = rank (transpose of a) Showing that A-transpose x A is invertible. Matrices can be used to perform a wide variety of transformations on data, which makes them powerful tools in many real-world applications. For example, matrices are often used in computer graphics to rotate, scale, and translate images and vectors.By Lemma [lem:005237], this shows that every invertible matrix \(A\) is a product of elementary matrices. Since elementary matrices are invertible (again by Lemma [lem:005237]), this proves the following important characterization of invertible matrices. 005336 A square matrix is invertible if and only if it is a product of elementary matrices.

I tried everything like using the inverse etc. but couldn't find anything. I've tried to prove it by using E=€(I), where E is the elementary matrix and I is the identity matrix and € is the elementary row operation. Took transpose both sides etc. Still nothing.
