kernel_build_sparse R Documentation
Build sparse kernel matrix.
Description
This function calculates kernel matrix.
Usage
kernel_build_sparse(kerneltype, location, bandwidth, tol, ncores)
Arguments
kerneltype
The type of kernel to be used, either "gaussian", or "cauchy" for cauchy kernel, or "quadratic" for rational quadratic kernel.
location
A n by d matrix of cell/spot location coordinates.
bandwidth
A numeric value of bandwidth.
tol
A numeric value of cut-off value when building sparse kernel matrix.
ncores
A integer value of number of CPU cores to use when building sparse kernel matrix.
Value
The sparse kernel matrix for spatial relationship between locations.
