gaussianKernel
Gaussian kernel
Contents
Syntax
y = gaussianKernel(u);
Description
gaussianKernel(u) returns the result of gaussian kernel function for u argument.
The result of a function depends on argument u and is described by following equation:
Input arguments
- u - Integer or a double value that is an argument of kernel function. Note, that u can be a vector of arguments. In this case function returns vector of results.
Examples
Draw graph presented gaussian kernel. The input argument is a vector of doubles on the interval ranging from -3.5 to 3.5. Input vector contains 100 equally spaced elements.
u = linspace(-3.5, 3.5); y = gaussianKernel(u); plot(u, y, '.-'); xlabel('u'); ylabel('y(u)'); title('Gaussian kernel');
