matrix calculation

[P.van Groenestijn]

Dear list,

Hi Marta,


As a result of some calculation I found this matrix, called mat:
mat
6
8
6

Could anyone help me to find a syntax that results in the following output
scalar, called res:
res
132

132 is the result of (6*8) + (6*6) + (8*6) in other words each element of
the matrix is multiplicated with each other. It would be nice when I can
also use the syntax in other examples (for example when the matrix here
called mat, has 5 elements).

Any help will be highly appreciated!!
