| Description: | Computes the rescaled (multivariate) Gaussian kernel ngau(u) = 5.*gau(5.*u). |
| Usage: | y = ngau(x) | |
| Input: | ||
| x | n x p matrix (or array) | |
| Output: | ||
| y | n x 1 matrix (or array) | |

A two port display is opened with a one dimensional and a two dimensional gaussian kernel
