I need to create an array of random integers. The array must consist of at least two numbers greater than one but there is no maximum array length. The elements of the array need to sum to less than 46. Thanks for your help.

Bill -
If you know n in advance, then this is pertinent information, although still insufficient. n is not simply random. It is arbitrary, but known.
What do you do when n is 16? You need to explain these things, otherwise, one is forced to guess what you want to do.
So can we assume that n is given by the user. Then you want to come up with the number of cards in each pile, that then sums to n? Must each number be greater than 2? How large can any single pile of cards then be?

John,
I see what your asking and I should have been more clear. Sorry, I'm still new at this.
Let's assume that the user inputs n which is an arbitrary integer between 1 and 45, inclusive. The code should then "randomly" parse the input into an array of smaller integers. There are no restrictions on the length of the array or the size of each element, except that the elements need to be integers and need to sum to n.
Hopefully that's a bit more clear. Thanks for your help.

I was about the say the same thing as Steven. Because it's card dealing, you need to use randperm(), not randi(). See my two attached car dealing demos.

If you're looking to shuffle a deck of cards, use randperm. Once you have a vector representing the shuffled deck of cards, use indexing to extract subsets of the vector to represent each of your piles.
