Hi,
I am surprised at this code. The line containing the sqrt is
generating lot's of errors. Its the only place in the code (it is line
61) where I am getting errors.
VectorXf mu[framesAfterCDS],sigma[framesAfterCDS];
//framesAfterCDS is a compile time constant
for(i=0; i<framesAfterCDS; i++)
{
mu[i]=x_accum[i]*(1.0/N);
sigma[i]=(x2_accum[i]*(1.0/N)-mu[i].cwise()*mu[i]);
sigma[i]=sigma[i].cwise().sqrt();
}

The error is there with both the 2.0.2 and dev branch.
Can somebody help me?
