kernel_build: Build kernel matrix.
In shangll123/SpatialPCA: Spatially Aware Dimension Reduction for Spatial Transcriptomics
kernel_build R Documentation
Build kernel matrix.
Description
This function calculates kernel matrix from spatial locations.
Usage
kernel_build(kerneltype = "gaussian", location, bandwidth)
Arguments
kerneltype
The type of kernel to be used, either "gaussian", or "cauchy" for cauchy kernel, or "quadratic" for rational quadratic kernel, and "delaunday" for gaussian kernel built with non-linear Delaunay triangulation based distance.
location
A n by d matrix of cell/spot location coordinates.
bandwidth
A numeric value of bandwidth.
Value
The kernel matrix for spatial relationship between locations.
