    Now that we have relational operators and if statements, let’s start writing the program.

    Here are the steps we will follow to develop the program incrementally:

    1. Write a script named findtriples.m and start with a loop that enumerates values of a and displays them.
    2. Write a second loop that enumerates values of b and a third loop that enumerates values of c.
    3. Use the if statement from the previous section to check whether a, b, and c form a Pythagorean triple.
    4. Display the values that pass the test.
    5. Transform the script into a function and make it take an input variable that specifies the range to search.

    Along the way, we’ll optimize the program to eliminate unnecessary work.
