Question

Homework 3 - Arrays, Masking, Systems of Equations, Plotting, and Numerical Methods Function Name: sysEq Inputs: 1. (double) An NxN array representing an A matrix 2. (double) An Nx1 vector representing a b matrix Outputs: 1. (double) An Nx1 vector representing the resulting x matrix Background: Whoo, who woulda thunk it? Actually useful things in MATLAB? You bet! This method of solving systems of linear equations is useful in a wide variety of places, from solving mesh currents in ECE classes to balancing reactor flow rates in ChBE classes. Now it is your job to make it happen. Function Description: Given an A and a b matrix, use left division to find the resulting x vector. Round your answer to two decimal places. Example [о, -21; 16, -36]; b -19; -15]; sysEq(A, b); [1.10; ө.90]; A х3 х %3D>

MATLAB code help!!

Answer 1

solution

\

SMatlab code sysEq.m function x = sysEq (A,b) x A\b; Edisplay the output decimal values sprintf ('4.2f\n ',x); x end Smain.m %representing an A matrix A 0-21 16 -361 %representing b matrix B -19; -15;]; Scall sysEquation

//output

Save it Show input Run it (F8) Absolute running time: 0.29 sec, cpu time: 0.56 sec, x = 1.10 0.90

//copyable code

%Matlab code

%sysEq.m

function x = sysEq(A,b)

x = A\b;

%display the output decimal values

x = sprintf('%.2f\n ',x);

end

%main.m

%representing an A matrix

A = [0 -21; 16 -36];

%representing b matrix

B = [-19; -15;];

%call sysEquation

x = sysEq(A,B)
