But first we need to write the question in Matrix form. Week 2 : Vector spaces and their properties, subspaces, basis and dimension, linear transformations. Then multiply A-1 by B (we can use the Matrix Calculator again): Just like on the Systems of Linear Equations page. Week 3 : Eigen values and eigen vectors, Calyey Haminton theorem, diagonalization. 2 Matrix Algebra Introduction. Subtraction gives 1 2 (A+AT)−B = C − 1 2 (A−AT). of NPTEL Video Courses : 84. Then (as shown on the Inverse of a Matrix page) the solution is this: It means that we can find the values of x, y and z (the X matrix) by multiplying the inverse of the A matrix by the B matrix. ), (I left the 1/determinant outside the matrix to make the numbers simpler).
