This module has two aims:1. to introduce basic matrix techniques for the formulation and solution of engineering problems. These techniques include the representation of geometric transformations, the power method to find eigenvalues and the solution of systems of differential equations. 2. to use partial differentiation to formulate and solve optimisation problems in several variables and to perform error analysis.
Representation by matrices. Dilation,projection,rotation and translation. Parametrized transformations. Inverse ofa matrix. Eigenvalues and eigenvectors and their geometric interpretation.
