Probability density function

mikedamike

Hi,

I have a probability density function defined by

1 / D x E . e^ABC/2

D is a single number
E is a determinant of a matrix
. is the dot product between the two sides of the function
e Im pretty sure is meant to be eulers constant
A is a 5x1 vector
B is a 5 x 5 matrix
C is a 5x1 vector

To my understanding eulers constant can only be raised to the power of a single number
My question is that how can the second half of the equation be solved if i require e^ABC/2 (which is effectivly a 5x1 matrix / 2)?

Can any one help me with this ?

Thanks in advance
Regards
Mike

ABC looks like a scalar to me. BC is a vector, so I presume that the last step is a dot product of A with BC.
