The provided MATLAB MEX functions are

ddm_fpt: computed the first-passage time density for symmetric bounds. See ddm_fpt.m for usage information.

ddm_fpt_full: computes the first-passage time density for arbitrary bounds. See ddm_fpt_full.m for usage information.

ddm_rand_sym: samples first-passage time and boundary from diffusion models with symmetric bounds. See ddm_rand_sym.m for usage information.

ddm_rand_asym: samples first-passage time and boundary from diffusion models with asymmetric bounds. See ddm_rand_asym.m for usage information.

Usage

The MATLAB MEX functions need to be compiled before use. To do so, run

mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_fpt.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_fpt_full.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_rand_sym.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_rand_asym.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_rand_full.cpp ../src/ddm_fpt_lib.cpp

at the MATLAB prompt. Alternatively, the files can be compiled at the shell. Do do so, use

mex CXXFLAGS="$CXXFLAGS -std=c++11" ddm_fpt.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS="$CXXFLAGS -std=c++11" ddm_fpt_full.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS="$CXXFLAGS -std=c++11" ddm_rand_sym.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS="$CXXFLAGS -std=c++11" ddm_rand_asym.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_rand_full.cpp ../src/ddm_fpt_lib.cpp

at the Windows Command Prompt (using double quotes, (")), or

mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_fpt.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_fpt_full.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_rand_sym.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_rand_asym.cpp ../src/ddm_fpt_lib.cpp
mex CXXFLAGS='$CXXFLAGS -std=c++11' ddm_rand_full.cpp ../src/ddm_fpt_lib.cpp

at the Mac and Linux shell command line (using single quotes (')). Note that, for older versions of MATLAB, all occurences of CXXFLAGS might need to be replaced with CFLAGS.

The location of the mex executable and exact syntax for specifying the compiler flags might be depend on OS and installation details.
