Matlab inverse matrix command

This function computes the inverse of a square matrix. This is used while solving linear equations. We can compute the inverse of a matrix by passing it to inv. Example 3: This example uses a singular matrix and tries to find its inverse. It will show a warning that the matrix is a singular matrix. Skip to content. Change Language.

Not every square matrix has an inverse. For example these 3x3 matrices do not have inverses:. The rank of a matrix is the number of independent rows. Since B has 3 rows and columns and its rank is 3, B has full rank and is non-singular. Another characteristic of a square matrix is its determinant. When the determinant is not 0, it has full rank. It doesn't matter whether the determinant is positive or negative. When the determinant is not 0, the matrix is nonsingular and can be inverted.
