dimensions) by C = A + B.. The sum is defined by adding entries with the same indices [pic] over all i and j. Example: [pic] Subtraction of Matrices Subtraction is performed in analogous way. Example: [pic] Scalar multiplication To multiply a matrix with a real number, we multiply each element with this number. Example: [pic] Multiplication of a row vector by a column vector This multiplication is only possible if the row vector and the column vector have the same number of elements. To multiply

2 Question One Compare and contrast The Matrix with the readings from Plato and Descartes. What are some similarities and differences? The Matrix describes a fictitious possibility of a virtual existence of the world and especially the world’s human population, unbeknownst by the majority of people involved in the virtual reality known as the Matrix. Certain players in the Matrix scenario are awakened to the proposition that perhaps their life experience

▪ Description [pic] ▪ Executive Summary ▪ Content Page ▪ Introduction The commercial aircraft engine consists of 3 major modules namely the Fan, Core and the Low Pressure Turbine (LPT). Each module will then be split into sub modules before it is stripped into individual parts. The engine is made up of thousands of parts put together and a typical shop visit (input, repair/upgrade, assembly, testing) will take approximately 60 days to complete. The

Linear Least Squares Suppose we are given a set of data points {(xi , fi )}, i = 1, . . . , n. These could be measurements from an experiment or obtained simply by evaluating a function at some points. You have seen that we can interpolate these points, i.e., either find a polynomial of degree ≤ (n − 1) which passes through all n points or we can use a continuous piecewise interpolant of the data which is usually a better approach. How, it might be the case that we know that these data points should

CHAPTER ONE 1.1 INTRODUCTION A casual look at the published empirical work in business and econometric will reveal that many economic relationships are of single –equation type. In such models, one variable (the dependent variable Y) is expressed as a linear function of one or more other variables (the explanatory variables, the X’s). An implicit assumption is that the cause and effect relationship, if any , between Y and X’s is unidirectional. The explanatory variables are the cause and the
