So if I understand what you are trying to do..you are doing something like

the following:

X = randn(200);

det(cov(X))

And then what this returns is a number very close to (or equal to) 0.

Right?

And I guess your logic is that since X is iid Gaussian (of say var 1), you

expect cov_X to be identity

matrix and so det should be 200, not 0.

Is that the problem?
