Matrices, rotation matrices in the plane and in space, algebra and geometric properties. Linear equations, row operations on matrices, the row echelon form. Homogenous systems of equations, consistency conditions, general solution. Inverse matrices. Vector spaces, sub-spaces, linear dependence and linear independence. Bases and the change of bases, row spaces of matrices, column equivalence, row-column equivalence, equivalence relations and canonical forms of matrices.
