triinv
Inverse of the triangular cumulative distribution function (iCDF).
For each element of p, compute the quantile (the inverse of the CDF) of
the triangular distribution with parameters a, b, and c on
the interval [a, b]
. The size of x is the common
size of the input arguments. A scalar input functions as a constant matrix
of the same size as the other inputs.
