inv

    Last Modified: March 15, 2017

    Computes the inverse of a square matrix.

    Syntax

    c = inv(a)

    Inputs

    a

    Square matrix. If a is singular, or has a determinant of zero, MathScript returns an error. If the reciprocal of the infinity norm of a is less than sqrt(eps), MathScript generates a warning because the inverse might be inaccurate. Consider checking the value of the inverse using inv(a)*a.

    Outputs

    c

    Inverse of a. c is a square matrix.

    Matrices within larger Expressions

    Use the / and \ operators if you multiply a matrix inverse by another matrix within larger expressions. For example, use A\B instead of inv(A)*B and use B/A instead of B*inv(A).

    D = [3, 2, -1; 1, 6, 3; 2, -4, 0]
    D_INV = inv(D)
    RESULT = D*D_INV
