Your file must begin with the function definition

Due: EOC (End of Class)

Goal
In this lab, we will use strfind() to take a single line of text and break it up into a user defined number of
words per line.

Setup

Create a new function file called textwrap.m.
Your file must begin with the function definition line, Help Line, and the specified information:

Requirements
This function takes in two parameters. The first input parameter is a string variable of only one row. If
there are multiple rows, throw an error. The second parameter is the number of words per row, it
should be a scalar integer value greater than 1.
Your function should perform the following:
1. Determine the number of words in the string
2. Using the user’s input for the number of words per line, calculate the number of lines
3. Create rows of words (from the original string) in a string array by concatenating vertically
a. Start by creating just the first line.
b. Create a loop that loops from the second line, until the second-to-last line
i. Determine the next line of text using the words-per-line and the original string
ii. Vertically concatenate the previous lines with this new line
c. Once the loop is over, add on the last line of the text (it may or may not have the same
number of words as the previous lines)
4. Give the vertically concatenated string array as the output

Sample output
Below is the sample output.

>> str = ‘It was the best of times, it was the worst of times, it was the age
of wisdom, it was the age of foolishness, it was the epoch of belief, it was
the epoch of incredulity, it was the season of Light, it was the season of
Darkness, it was the spring of hope, it was the winter of despair, we had
everything before us, we had nothing before us, we were all going direct to
Heaven, we were all going direct the other way–in short, the period was so
far like the present period, that some of its noisiest authorities insisted
on its being received, for good or for evil, in the superlative degree of
comparison only.’
