Error: Matrices Must Agree

Hello,
I am attempting to run the below function but I keep getting the error "Error using - : Matrices must agree". I have added as many periods as I thought I needed and still can't get it to work. x1 and x2 are both scalar values. Uunder0 is a (2x1) matrix. The error occurs in my funTRmvn function.
Any help please:
a1 = 2
a2 = 3
b1 = 1
b2 = 4
%function 4
funTRmvn = @(x1,x2) (1./(((2*pi)^(P./2)).*((det(Sigma0)).^(1./2)))).*(exp(((transpose(Uunder0-x1))).*(inv(Sigma0)).*(x2-Uunder0)));
TRmvn = integral2(funTRmvn,a1,b1,a2,b2);
Thanks Kam

Please post a complete copy of the error message.

Provide values for
P, Uunder0, Sigma0
Do they "agree"? Is funTRmvn supposed to return a real value?
Proposal:
  • rename a1, a2, b1 and b2 to xmin, xmax, ymin and ymax
  • implement funTRmvn as an ordinary function and debug it carefully
