k-Wave Toolbox


Calculate acoustic field for CW source using C++ code.


See acousticFieldPropagator.


acousticFieldPropagatorC provides an interface to the C++ version of acousticFieldPropagator (called acousticFieldPropagator-OMP). The function works by appending the optional input 'SaveToDisk' to the user inputs and then calling acousticFieldPropagator to save the input files to disk. The C++ code is run using the system command. The output files are then automatically loaded from disk and returned in the same fashion as acousticFieldPropagator. The input and output files are saved to the temporary directory native to the operating system, and are deleted after the function runs.

This function requires the C++ binary/executable of acousticFieldPropagator-OMP to be downloaded from http://www.k-wave.org/download.php and placed in the "binaries" directory of the k-Wave toolbox. Alternatively, the name and location of the binary can be specified using the optional input parameters 'BinaryName' and 'BinariesPath'.

Optional Inputs

Optional 'string', value pairs that may be used to modify the default computational settings.

Input Valid Settings Default Description
'BinaryName' (string) 'acousticFieldPropagator-OMP' on linux and 'acousticFieldPropagator-OMP.exe' on windows Name of the binary file.
'BinaryPath' (string) 'binaries/' Path of the binary file.
'DataName' (string) 'kwave_[input/output]_data_[date].h5' Prefix used to generate a custom name for the input and output data files (this is appended with '_input.h5' and '_output.h5').
'DataPath' (string) path returned by tempdir Location of the folder where the input and output HDF5 files should be stored.
'DeleteData' (Boolean scalar) true Boolean controlling whether the input and output HDF5 files should be deleted after running the simulation.
