Unity+ Posted August 13, 2013 Posted August 13, 2013 I am assuming that since the amount of arrangements possible for a set of elements is equal to the amount of elements within the set to the factorial, that for a matrix it would be the area of the matrix factorial. Is this true?
studiot Posted August 13, 2013 Posted August 13, 2013 I'm not sure what you are trying to say but it doesn't sound right. Area of a matrix?
Unity+ Posted August 13, 2013 Author Posted August 13, 2013 Yes the Area. A matrix can be a k by d, where k is the width and d is the height. Multiply them to get the area. [math]\begin{bmatrix} 3&2 &5 \\ 1& 3 &5 \\ 6&3 & 4 \end{bmatrix}=A_{3\times 3}[/math]
Bignose Posted August 13, 2013 Posted August 13, 2013 Unity, this is why you have to be very careful with your terminology. I don't think I had ever heard anyone call the total number of elements in a matrix the 'area' before. It is especially confusing since there are matrix operations that can calculate areas, e.g. usually via a determinant. And, yes, if there are no restrictions on the ordering of the elements (i.e. no symmetry requirements or similar), then it would be the factorial of the product of rows x columns 2

I guess terminology for me is a bit confusing sometimes.
