CONVUS: An efficient package for calculating three-dimensional convolution-type integrals

Description

CONVUS is a program for the efficient calculation of integrals of the form:

Z(r₁,r₂) = Integrate { d³r₃ p(r₃) X(r₁,r₃) Y(r₂,r₃) }

Such integrals appear in many calculations in physics and chemistry, specially when studying many-body problems of finite systems. Two versions requiring different amounts of memory are available.
