IncBeta: Incomplete Beta function of a matrix argument
Description
Evaluates the incomplete Beta function of a matrix argument.
Usage
IncBeta(m, a, b, x)
Value
A real or a complex number.
Arguments
m
truncation weight of the summation, a positive integer
a, b
real or complex parameters with Re(a)>(p-1)/2 and
Re(b)>(p-1)/2, where p is the dimension (the order of the
matrix)
x
either a real positive symmetric matrix or a complex positive
Hermitian matrix "smaller" than the identity matrix (i.e. I-x is
positive), or a numeric or complex vector, the eigenvalues of the matrix
