Hello Mark,<br>
<br>
If you can't find an open source math package that meets your needs
you may want to take a look at CenterSpace's NMath Library. The
library is .Net compatible. See:<br>
<a class="moz-txt-link-freetext" href="http://www.centerspace.net/products/nmath/">http://www.centerspace.net/products/nmath/</a><br>
<br>
Cost: $995 for Nmath or $1295 for NMath and a statistical library.<br>
