O Solving Systems of Linear Equations using Inverse of a Matrix & Elementary Row Operations Consider: [pic] be a linear system of n equations in n unknowns and let [pic] be the coefficient matrix so that we can write the given system as AX = B where [pic]. If [pic] then the system has a unique solution. To solve for SLE of the form, [pic], [pic]. Recall: For SLE in 2 unknowns: For SLE in 3 unknowns: given [pic] , given [pic]

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

Program 1: Write a program to copy the contents of one array into another in the reverse order. Code: #include<stdio.h> int main() { int arry1[10],arry2[10]={0},i,j; printf("Enter the elements of array: \n"); for(i=0;i<10;i++) { printf("Enter element %d:",i+1); scanf("%d",&arry1[i]); } i=0; for(j=9;j>=0;j--) { arry2[j]=arry1[i]; i+=1; } printf("Array elements in reverse order are: \n"); for(i=0;i<10;i++)

▪ 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
