Explanation of the code writing above and statements for task 1.
The clear function
This function was used to clear the command windows and remove any items from the workspace by freeing the systems memory.
The clc function
I used the clc function to clear the command window from any errors generated during my debugging of my code any time I run it.
The Input function
This function
