toms462, a MATLAB code which evaluates the upper right tail of the bivariate normal distribution; that is, the probability that normal variables X and Y with correlation R will satisfy H <= X and K <= Y.
The text of many ACM TOMS algorithms is available online through ACM: https://calgo.acm.org/ or NETLIB: https://www.netlib.org/toms/index.html.
toms462 is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
owen, a MATLAB code which evaluates owen's t function.
prob, a MATLAB code which contains a number of routines for evaluating cumulative distribution functions.
test_values, a MATLAB code which supplies test values of various mathematical functions.
