If it is not a square matrix.
You cannot invert a square matrix if it is singular. That means that at least one of the rows of the matrix can be expressed as a linear combination of the other rows.
A simple test is that a matrix cannot be inverted if its determinant is zero.

What is idempotent matrix?
An idempotent matrix is a matrix which gives the same matrix if we multiply with the same. in simple words,square of the matrix is equal to the same matrix. if M is our matrix,then MM=M. then M is a idempotent matrix.
What is a reduced matrix?
Reduced matrix is a matrix where the elements of the matrix is reduced by eliminating the elements in the row which its aim is to make an identity matrix.
How are the inverse matrix and identity matrix related?
If an identity matrix is the answer to a problem under matrix multiplication, then each of the two matrices is an inverse matrix of the other.
How do you solve simultaneous equations using matrices?
There are many ways of doing this. For example Gaussian elimination, diagonalising, but the simplest to explain is matrix inversion (I'm assuming some knowledge of matrices here, and unfortunately some of the matrix formatting is a little off due to limitations in the editor): Any system of simultaneous equations can be rewritten as the matrix equation A.v = u The coefficients of the variables become the entries in the square matrix, A. To solve the matrix equation we need to invert A, and then multiply by the inverse, giving us I.v = A-1.u where I is the identity matrix. As an example take the following system of equations: 2x - 3y = 1 4x - 5y = 5 The matrix version of this equation is { 2 -3 } { x } = { 1 } { 4 -5 } { y } { 5 } A v u It's clear that if you multiply out the matrix row by row, you get the original set of equations. In our case I = { 1 0 } { 0 1 } A-1 = { -2.5 1.5 } { -2 1 } (Finding the inverse of a matrix is a whole other question) so A-1.u = { 5 } { 3 } Therefore we have x = 5, and y = 3. Inversion of A is the most difficult step, though this can easily be done with a computer.

How do you find transportation of matrix?
Invert rows and columns to get the transpose of a matrix
How do you find original matrix from its inverse matrix?
To find the original matrix of an inverted matrix, simply invert it again. Consider A^-1^-1 = A^1 = A
How can systems of equations be solved?
It depends on your level of expertise. The simplest method is to invert the matrix of coefficients.
What is the difference between invert level and invert elevation?
Invert Level and Invert Elevation are one in the same. Invert Level = Invert Elevation (IE).

How do find matrix inverse of 4cross 4matrix?
Next to your 4x4 matrix, place the 4x4 identity matrix on the right and adjoined to the one you want to invert. Now you can use row operations and change your original matrix on the left to a 4x4 identity matrix. Each time you do a row operation, make sure you do the same thing to the rows of the original identity matrix. You end up with the identity now on the left and the inverse on the right. You can also calculate the inverse using the adjoint. The adjoint matrix is computed by taking the transpose of a matrix where each element is cofactor of the corresponding element in the original matrix. You find the cofactor t of the matrix created by taking the original matrix and removing the row and column for the element you are calculating the cofactor of. The signs of the cofactors alternate, just as when computing the determinant
When was Nixon invert created?
