To invert the following matrix :
Matrix A =
1(Mat)aA!Xw
• Only square matrices (same number of rows and columns) can be inverted.
Trying to invert a matrix that is not square produces an error.
• A matrix with a value of zero cannot be inverted. Trying to invert a matrix with
value of zero produces an error.
• Calculation precision is affected for matrices whose value is near zero.
• A matrix being inverted must satisfy the conditions shown below.
