WEBA matrix X is invertible if there exists a matrix Y of the same size such that X Y = Y X = I n, where I n is the n-by-n identity matrix. The matrix Y is called the inverse of X. A matrix that has no inverse is singular. A square matrix is singular only when its determinant is …

Inverse of symbolic matrix - MATLAB inv - MathWorks
WEBFind the inverse of f using inv. The result is a symbolic matrix function of type symfunmatrix that accepts scalars, vectors, and matrices as its input arguments. fInv = inv(f) fInv(a0, A) = a 0 I 2 + A - 1. Convert the result from the symfunmatrix data type to the symfun data type using symfunmatrix2symfun.

Reduced row echelon form (Gauss-Jordan elimination) - MATLAB rref
WEBRow Reduction of Augmented Matrices. Use Gauss-Jordan elimination on augmented matrices to solve a linear system and calculate the matrix inverse. These techniques are mainly of academic interest, since there are more efficient and numerically stable ways to calculate these values. Create a 3-by-3 magic square matrix.
WEBSyntax. Y = inv(X) Description. Y = inv(X) returns the inverse of the square matrix X. A warning message is printed if X is badly scaled or nearly singular. In practice, it is seldom necessary to form the explicit inverse of a matrix. A frequent misuse of inv arises when solving the system of linear equation s .
