CFirstElementKernelNormalizer Class Reference

---

Detailed Description

Normalize the kernel by a constant obtained from the first element of the kernel matrix, i.e. .

useful if the kernel returns constant elements along the diagonal anyway and all one wants is to scale the kernel down to 1 on the diagonal.
