Learning C++/Unix

If you're up to setting up a Linux box, I suggest using gnu c++. If you have the latest version of Mandrake or Redhat, then everything is free and you have a KDE development environment that is not too dissimilar to MSoft.

It does make you want to play, though.I found the THE PRINCIPAL OF COMPUTATIONAL EQUIVALENCE interesting, if only what I understand of it appears to fly in the face of an interesting argument for non-computable thought made accessi...

Correlation Matrix

<t>I agree with Reza's point on positive definiteness. IfX = (X_i), v_i = Var(X_i), c_ij = Cov(X_i, Y_j), C = (c_ij)Then the correlation matrix Corr(X) = V C V, where V = diag{1/sqrt(vi)}. So if the covariance matrix is pd (or psd), so is the correlation matrix. Can test for positive definiteness by...

Therefore, and I may be wrong here, if you have some template_class<int> and another template_class<char>, the compiler will create two instantiations of template_class...gener...
