Q14. Typpedef struct circle
{
double radius;
double center_x;
double center_y;
} Circle;
Please write the statement needed to declare and initialize a structure of type Circle. The radius is 5, center x coordinate of 3.5, and center y coordinate of -5.2. Remember this requires only one line.
Q15. Write the MATLAB command needed to create a vector t→ that begins with -2 and progresses to 10 at increments of 0.25.
Now write a MATLAB statement to square each element in t→ and add five to the result.
Q16. Declare a structure for holding information about a car. It should hold the model name, year , and mileage.
Use typedef to give the structure a name that does not require struct when creating an instance of it.
Q17. a) Write a C statement to declare an array buff with 200 characters:
b) Write a C statement to declare a two dimensional array wind. The array must be able to hold a 5 by 6 table of data.
c) Write a C statement to declare an astray of four doubles g initialized with the value 1.8, 4, 12.98, and -0.3;
Q18. The U.S. Geological Survey is doing a survey of the Red River of the North. They are flying a UAV over the river and using a radar to get depths of the river bed. This is basically like taking depth readings along a slice of the river. The flow rate of the river is proportional to the area of the slices. To be able to predict river levels they need to read in the data captured by the UAV and calculate the area of the slices. Then print out the corresponding areas. To get the area of a slice, multiply each river depth by the radar beams width, 100 ft, and sum the values. There are three readings per slice.
Step 1: State the problem
Step 2: Input and outputs
Step 3: Work hand example
Step 4: Develop the algorithm
Q19. The MATLAB starting point for a function is:
function ( output_args ) = Untitled( input_args )
%UNTITLED Summary of this function goes here
% Detailed explanation goes here
end
a) Please give the first line to a MATLAB function that has three inputs: a, h, and c. The function should return the sum and average of the corresponding numbers. The function's name should be "sum_ave_three.
b) Provide the body of the function that calculates each value being returned.
c) Call the created function to find the sum and average of 3, 7, and 2. Store the results in my_sum and my_ave.
Q20. Describe two of the three types of data files. Provide a pro and con of each.
Q21. Please convert the following to MATLAB statements. Assume t and x are vectors.
a) 5+6*31.85/35+711.5
b) g = 25/1.3*t3 - 2.9*t2+28
c) w = 1.54 * sin2(x * π) + 0.678 * sin (x * π) + 15.32
