Question

For each of the problems in this homework assignment, write a separate MATLAB m-file. The name of each m-file must be exactly as specified in the corresponding problem statement. Submit your m-files by uploading to Blackboard before the due date A p-file (an encrypted script file) for each of these problems is available on the Homework page of the course website. You can download these files and run them from the command line to see how your code should behave. Make the behavior of your code match that of the p-files. For each of these problems in this assignment, you may want to create a separate m-file to use as a test bench. In these test bench m-files, you can define the vector or matrix, x, and call your m-file that operates on that vector or matrix 1) Filename: MAE1090 HW7 1.m Write an m-file that determines the maximum value in a vector, x, and stores that maximum value as the variable y. Your m-file should work for both row and column vectors. For the purpose of testing and grading your m-file: DO NOT issue a clear command at the start of your m-file DO NOT define the vector x within your m-file. That vector should exist in the workspace prior to executing your m-file. Do not display y. This will be done by the script the grader uses to test your m-file.

Explanation / Answer

Here is the code for problem 1:

function y = MAE1090_HW7_1(x)

% Write an m-file that determines the maximum value in the vector x, and

% stores the maximum value as the variable y. Your m-file should work for

% both row and column vectors.

[rows, cols] = size(x);

y = x(1, 1);

for i = 1 : rows

for j = 1 : cols

if x(i, j) > y

y = x(i, j);

end

end

end

end

Code for problem 2:

function [i, j] = MAE1090_HW7_2(x)

% Write an m-file that determines the row and column indices for all

% non-zero elements in matrix x. Row indices should be stored to the

% variable i, and column indices should be stored to the variable j.

next = 1;

[rows, cols] = size(x);

for y = 1 : rows

for z = 1 : cols

if x(y, z) == 0

i(next) = y;

j(next) = z;

end

end

end

end

Code for Problem 3:

function y = MAE1090_HW7_3(x)

% Write an m-file that sorts a vector, x, and stores the sorted values in

% a vector, y.

y = x;

for i = 1 : length(y)-1

for j = 1 : length(y)-i

if y(j) > y(j+1)

temp = y(j);

y(j) = y(j+1);

y(j+1) = temp;

end

end

end

end
