Date: Jan 25, 2013 11:24 PM Author: Patrick D. Rockwell Subject: Calculating matrix permanent I've read how to calculate the permanent of a matrix,

but I found the notation hard to understand so I'd

Like a practical demonstration. For 2 by 2 matrices

It's easy. For example, the permanent of

2 4

9 6

Is 2*6+4*9=36+12=48

But what about

5 3 1

8 2 4

7 9 6

What is48 the permanent of the above matrix

and how do you calculate it?
