The Gravitational Radiation Toolbox provides a Matlab interface to both GRASP and the Frame Library. The toolbox consists of Matlab m-files and mex-files. The m-files are written in Matlab's native language and are interpreted. The mex-files are written in C and are compiled. The mex-files take input from the user via Matlab and then format it and pass it to the corresponding GRASP routine. The GRASP output is then formatted and passed back into Matlab. The function names and calling methods have been made to resemble those of their corresponding GRASP functions with the main difference being that the Matlab user need not be concerned with memory management and pointers. These functions can be used from the command line, within other m-files, or via a GUI front end called GRtool. Currently the toolbox addresses only the detection and simulation of gravitational radiation from binary inspirals.
When installing GRASP you have the option of installing the Gravitational Radiation Toolbox as well. If you have not done this see sections and for installation instructions.
