Linear Algebra

LINEAR ALGEBRA performs computations associated with real matrices, including solution of Linear Systems of equations (even least squares solution of over-determined or inconsistent systems and solution by LU factors), Matrix operations (add, subtract, multiply), finding the determinant, trace, inverse, adjoint, QR and LU factors, eigenvalues and eigenvectors, establish the definiteness of a Symmetric matrix, perform scalar multiplication, transposition, shift, Create matrices of zeroes or ones, identity, symmetric or general matrices.
