The two-dimensional Gaussian function can be obtained by composing two one-dimensional Gaussians. I changed your code slightly so that it would compile (and not optimize away the unused kernel): #include int main () { int rows = 20000, cols = 20000; const auto kernel = getGaussianKernel (rows, cols, 50, 50 ); …

The multivariate normal, multinormal or Gaussian distribution is a generalization of the one-dimensional normal distribution to higher dimensions. Such a distribution is specified by its mean and covariance matrix. These parameters are analogous to the mean (average or “center ...
