Math library wanted on SCO UNIX

[cav]

We would like to know if there is a commercial (supported)
tool which satisfies the following requirements:

1) runs under SCO Unix environment

2) performs statistical analysis of processed data:
	- extrapolation
	- interpolation
	- curve fitting
	- correlation and regression analysis
	- sorting

3) performs specific mathematical applications:
	- Fourier analysis
	- finite elements calculus
	- numerical methods for integral calculus
	- solution of partial derivatives differential equations


Please send E-mail. Thanks in advance,
                                        Massimo Cavallini
