Question

Need help with this Matlab program

%% Exercise 1

% NOTE: Please suppress output--i.e., use a semicolon ';' at the end of any
% commands for which the output is not necessary to answer the question.
% Delete these notes before turning in.

% Define input variable theta as discretized row vector (i.e., array).
theta = ??;

% Define radius.
r = ??;

% Define x and y in terms of theta and r.
x = ??;
y = ??;

% Check that x and y satisfy the equation of a circle.

%%
% Explain results here. Do x and y satisfy the equation of a circle? Why or
% why not? How does the vector output at the end confirm your answer?
% Notice I did not include text in the same line where the double-comment
% is. What this accomplishes is it does not add a title or create a new
% section in the table of contents when you publish. Using single %
% starting in the line after the %% turns the comments black as opposed to
% green.

%% Exercise 2

% Define t-vector.
t = ??;

% Define y-vector.
y = ??

%%
% Part (a)

% Plot results (should have 3 plots total).
figure;
plot(??);
title('??')

%%
% Part (b)

% Plot results as data points only and as data points with line.
figure; % creates a new figure window for next plot
plot(??);
title('??')

figure; % creates another figure window
plot(??);
title('??')

%% Exercise 3

% Create t-vector (choose enough elements so that plot is smooth!)
t = ??;

% Define x,y,z components in terms of t.
x = ??; y = ??; z = ??;

% Plot resuls.
figure;
plot??)

% NOTE: if graph does not look smooth, use more elements in your
% t-vector--i.e., use smaller stepsize between elements. Delete these notes
% before submission.

%% Exercise 4

% Define input variable as vector.
x = ??;

% Define y and z.
y = ??;
z = ??;

% Plot results.
figure;
plot(??)
axis tight;
grid on;

%% Exercise 5

% NOTE: you must create the M-file ex5.m separately and invoke it here in
% your main M-file (main file).

% Print out the code for your created M-file (do NOT submit M-file
% separately).

type 'ex5.m'

% Run your M-file--i.e., execute the M-file.

run 'ex5.m'

%% Exercise 6

% For part (b), you need to create a separate M-file (f.m) and invoke it in
% the main file, here. Erase these notes upon submission.

%%
% Part (a)

% Define g as anonymous function.
g = @(x,y)(??);

% Evaluate g at the given values of x and y

%%
% Part (b)

% Clear the function g out of the workspace.

% Print out g.m contents.
type 'g.m'

% Evaluate g at the given values of x and y
%% The End!!!
