Answer 2

Need suggestions. I was thinking about using a while loop and asking the user to input x, y, z values.

Answer 3

so basically do guess and check?

Answer 4

Yes, but I was just reading the lab and I need to load the CSV files.

Answer 5

guess and check is one way to do it, but it's very tedious and you may never actually get the answer no matter how hard you try to guess it

Answer 6

using rref is a much better way

Answer 7

well, I was going to use rref, but I wanted to ask the user to input values in for equation 1, equation 2, and equation 3.

Answer 8

This is my idea....

Answer 9

the values are drawn from the csv files

Answer 10

oh okay... So the values in the CSV are my inputs?

Answer 11

yes for the coefficients and right hand side

Answer 12

Okay thanks. Let me think about that more and I will get back to you later.

Answer 13

This is the assignment.

Answer 14

My work, please check.

clear, clc, close all; % clears all windows

% loads CSV files into matlab
matrixA = csvread('A.csv');
matrixB = csvread('B.csv');

% combining matrices A and B
matrixSystem = horzcat(matrixA, matrixB);

% solves the system of equations
S = rref(matrixSystem);

% extracting last column in S matrix
solveX = S(1, 4);
solveY = S(2, 4);
solveZ = S(3, 4);

% output displayed
fprintf('Equation 1: 1x + -2y + 3z = 7 \n');
fprintf('Equation 2: 2x + 1y + 1z = 4 \n');
fprintf('Equation 3: -3x + 2y + -2z = 1 \n\n');
fprintf('The solutions are as follows \n\n');
fprintf('x = %0.4f \n', solveX);
fprintf('y = %0.4f \n', solveY);
fprintf('z = %0.4f \n\n', solveZ);
