/**
* \ingroup opencl
* \defgroup opencl_kernel_generator OpenCL Kernel Generator
*
* The OpenCL kernel generator is used to combine multiple matrix operations into a
* single OpenCL kernel. This is much simpler than writing multi-operation kernels by
* hand.
*
* Because global GPU memory loads and stores are relativly slow compared to
* calculations in a kernel, using one kernel for multiple operations is faster than using one kernel
