Description

CuLab is a very intuitive and simple to use toolkit for LabVIEW designed to accelerate computationally intensive tasks on Nvidia GPUs.

The purpose of CuLab is to provide extensive API functions to accelerate mathematical operations, BLAS (Basic Linear Algebra Subroutine) functions and common signal processing functions (FFT/IFFT) on GPUs.
Almost all CuLab operation functions support all numeric data types.

The main idea of the toolkit is to provide simple mechanisms to accelerate any data processing code developed in LabVIEW on Nvidia GPUs.
