For example, if you had:

abc
def
ghi

Say I wanted the row and column of 'e', how would I do this? I have been looking everywhere for this and I just can't seem to find it. Please help. Thank you!

[rows, columns] = find(yourMatrix == e); % e is an integer.

If e is not an integer or power of 2, see the FAQ : http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F

You decide which position is the "first" one, and you index rows() and columns() at that same index. But how do you define which is the "first" ?

AB
BD

which 'B' is 'first' ?

The way that I want to implement this, is with a wordsearch. I have a 15x15 2 dimensional array filled with letters. I have created a function that runs checks throughout the array looking for the word a user inputs. With this, I am to return the row and column of the first letter of the word. So it would be like this:

 iuwekfasdkuhwqa
 kjdfjdjilihvjut
 injmatlabiliwtm
 ijghaddndldndld

And so on. The user would then use the function I created and input a word, in this case 'matlab'. The function would then output the row and column of 'm' (3rd row; 4th column). If you would like to see my code, I would gladly show you.
