cndkernel-class {qkerntool}

Class "cndkernel" "nonlkernel" "polykernel" "rbfkernel" "laplkernel"

Description

The built-in kernel classes in qkerntool

Objects from the Class

Objects can be created by calls of the form new("nonlkernel"), new{"polykernel"}, new{"rbfkernel"}, new{"laplkernel"}, new{"anokernel"}, new{"ratikernel"}, new{"multkernel"}, new{"invkernel"}, new{"wavkernel"}, new{"powkernel"}, new{"logkernel"}, new{"caukernel"}, new{"chikernel"}, new{"studkernel"},new{"norkernel"}

or by calling the nonlcnd,polycnd, rbfcnd, laplcnd, anocnd, raticnd, multcnd, invcnd, wavcnd, powcnd, logcnd, caucnd, chicnd, studcnd, norcnd functions etc..

Slots

.Data:
