示例1: gaussianKernel
import org.joml.Math; //导入方法依赖的package包/类
/**
* Generate a Gaussian convolution kernel with the given number of rows and columns, and store
* the factors in row-major order in <code>dest</code>.
*
* @param rows
* the number of rows (must be an odd number)
* @param cols
* the number of columns (must be an odd number)
* @param sigma
* determines how big the factors are at the center of distribution
* @param dest
* will hold the kernel factors in row-major order
