The Pythagorean theorem states that a^2 + b^2 = c^2
• Write a MATLAB program in a script file that finds all the combinations of triples a, b, and c that are positive integers all smaller or equal to 50 that satisfy the Pythagorean theorem. Display the results in a three-column table in which every row corresponds to one triple. The first three rows of the table are: 
   3 4 5
   5 12 13
   6 8 10

And rather than just paste in your homework assignment for us to do, what have you tried? Have you made an effort? If you cannot do so, then why should we?

Of course, if you cannot be bothered to do so, then we should get some credit for doing your homework. And while I know that you would honestly give us credit when you handed in your homework, a small part of me worries that you might not do so. So please add the e-mail address of your teacher. We can then send our solutions directly to that person.

Hint: one way is to try the brute force way of two (nested) for loops. See this FAQ also: http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F

The 2nd link is good advice in general, but I don't see that it applies in this case. Double arithmetic will be done exactly with integers of this size.

Here's a hint to get you started. Suppose you have two positive integers, a and b. How would you use matlab to determine whether or not the value a^2+b^2 is the square of another integer, c? If you can answer that question, you are well on your way to solving your problem.
