Use Matlab...

Use the given variables please...

Replace 0 and []....

%problem 1

disp('*****problem 1*****');

%height, width and depth values for test cases

h = [5 1 2];

w = [3 8 2];

d = [2 4 10];

%initializing results

sa = zeros(1,3);

vol = zeros(1,3);

%example of the left-hand side of the function call, assuming the function

%arguments are scalars. If the function arguments are arrays, remove the

%index

[vol(1), sa(1)] = dummy(); %replace dummy with your function name

%problem 2

disp('*****problem 2*****');

prob2a1 = 0;

prob2a2 = 0;

x = [];

prob2b = dummy(); %replace dummy with your function name

figure(1);

Application 4: User-defined functions and plotting Designed to test skills: user-defined functions (with multiple inputs and/or multiple outputs), writing functions (function main, function files), plotting multiple data series ENGR 1221 Note: Present results using fprintf()and comment your code throughout. Write a function that will compute the volume and surface area of a rectangular prism when provided with the object's 3 numerical dimensions. In other words, the function should be given three inputs (height, width and depth) and return two outputs (the volume and surface area, in that order). Show the following test cases: 1. a. height: 5 width:3 depth: 2 b. heignt:1 width:8 depth:4 c. height: 2 width:2 depth:10 The script should call the function 3 times and store the results of the three test cases in two row vectors called vol and sa. Function specifications Input arguments: length, width, height- all scalars. (Order does not matter) Output arguments: volume, area - both scalars. (Must be in this order) OPTIONAL: If you prefer, you can write the function such that the input and output arguments are arrays; in that case, only one call to the function is necessary. 2. Write a user-defined function (not an anonymous function) for the following math function: y(x) = 0.9x"e-0.1x-15x25x The function should accept x as its input and it should return y. Write the function such thatx can be a vector. a. Use the function to calculate y(-2) and y(4) b. Use the function to make a plot of y(x) for -3 3x s5 (use linspace with 100 values for x)
