[R] numerical integration of a bivariate function

[Hicham Mezouara]

hello
I work on
the probabilities of bivariate normal distribution. I need
integrate  the
following function.
f (x, y) = exp [- (x ^ 2 + y ^ 2 + x * y)] with - ∞ ≤ x ≤
7.44 and - ∞ ≤ y ≤ 1.44   , either software R or  matlab Version R 
2009a
Thank you
for helping me
Regards
