Question

Use the anonymous function layout to create the function created in below question .Call the function r.

Create a function with one input a and one output called b. The function name will be squarea. The function will take the input, a, and square it so that the output is b. Use function handles to set squarea equal to f.
If a = 3, show how you would put this command in the command window.

Answer 1

Here is how you can define the function:

f = (at)(a) a²;

To call the function with an input of a = 3, you can use the following command in the MATLAB command window:

b = f(3);

This will assign the value 9 to the variable b.

Step-by-step explanation:

To create the function "s`quarea" that takes an input "a" and squares it to produce the output "b," you can use an anonymous function in MATLAB.

Here's how you can do it:

1. Define the anonymous function by using the "(at)" symbol followed by the input variable and the operation you want to perform on it. In this case, the operation is squaring the input. The syntax would be:

```matlab

s`quarea = (at)(a) a²;

```

2. The function handle "s`quarea" is now set equal to the anonymous function. This allows you to call the function by using the handle "s`quarea" later on.

To call the function with an input value of 3, you can use the following command in the MATLAB Command Window:

```matlab

r = squarea(3);

```

The value of "r" will be the square of the input value, which in this case is 3. So, "r" will be equal to 9.
