kspaceFirstOrder3DC

3D time-domain simulation of wave propagation using C++ code

Syntax

See kspaceFirstOrder3D.

Description

kspaceFirstOrder3DC provides an blind interface to the C++ version of kspaceFirstOrder3D (called kspaceFirstOrder3D-OMP). The function works by appending the optional input 'SaveToDisk' to the user inputs and then calling kspaceFirstOrder3D to save the input files to disk. The contents of sensor.record (if set) are parsed as input flags, and 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 kspaceFirstOrder3D. 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 kspaceFirstOrder3D-OMP to be downloaded from www.k-wave.org/download.php and placed in the "binaries" directory of the k-Wave toolbox.

Note, not all input options are currently supported, and all display options are ignored (only command line outputs are given). See the k-Wave user manual for more information.

This function is not recommended for large simulations, as the input variables will reside twice in main memory (once in MATLAB, and once in C++). For large simulations, the C++ code should be called outside of MATLAB. Again, see the k-Wave manual for more information.

Optional Inputs

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

Input Valid Settings Default Description

'BinaryName'

(string)

'kspaceFirstOrder3D-OMP' on linux and 'kspaceFirstOrder3D-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.
