Input Function

7.1 Create an M-file that prompts the user to enter a value of x and then calculates the value of sin (x).

7.2 Create an M-file that prompts the user to enter a matrix and then use the max function to determine the largest value entered. Use the following matrix to test your program:

(1, 5, 3, 8, 9, 22)

7.9 Use fprintf to create the multiplication tables from 1 to 13 for the num¬ber 6. Your table should look like this.

1 times 6 is 6
2 times 6 is 12
3 times 6 is 18

LOGICAL OPERATORS: FIND

8.1 A sensor that monitors the temperature of a backyard hot tub records the data shown in Table 8.5.

Table 8.5 Hot-Tub Temperature Data

(b) Use the length function with the results from pan (a) to determine how many times the maximum allowable temperature was exceeded.

Problem 8.1

hot_tub=[100,101,102,103,103,104,104,105,106,...
106,106,105,104,103,101,100,99,100,102,...
104,106,107,105,104,104];

8.6 Create a function called g that satisfies the following criteria:

For x < -π,                        g(x) = -1
For x ≥ π and x ≤ π,           g(x) = cos (x)
For x > IT,                         g(x) = -1

Plot your results for values of x from -2π to +2π. Choose your spacing to create a smooth curve.

8.10 Create a program that first prompts the user to enter a value for x and then prompts the user to enter a value for y. If the value of x is greater than the value of y, send a message to the command window telling the user that x > y. If x is less than or equal to y, send a message to the command win¬dow telling the user that y > = x.

8.16 At a local university, each engineering major requires a different number of credits for graduation. For example, recently the requirements were as follows:

Prompt the user to select an engineering program from a menu. Use a switch/case structure to send the minimum number of credits required for graduation back to the command window.
