Does Prime 3.1 Express have cfft and icfft functions?

After the free trial period ends do the cfft and icfft functions remain enabled?

This page, http://www.ptc.com/engineering-math-software/mathcad/worksheets/advanced-engineering-math, implies that Fourier transforms are considered "Advanced engineering math", and are therefore not included in Prime Express. I have no easy way to verify that though,

Hi.

I think that all functions are available in Prime 3.1 Express. Limitations are described on PTC Mathcad Comparison Chart | PTC page.

Thanks to all for the responses!

Not the answer I was hoping to hear. We design LED driver chips and want to disseminate a Mathcad worksheet to enable our customers to calculate flicker after FFT filtering. It would have given exposure to PTC Mathcad among our customers if it worked.

The answer is very ambiguous; the comparison chart shows that all features with an asterisk were not available after 30 days. The  "Advanced Engineering Mathematics" feature shows as not available but has no asterisk. I think it would be better to specifically list functions that are disabled after 30 days.

I'll have to look for a freebie clone we can use.

Much thanks!

PTC very proudly recently advertised the ability to deploy a :Gateway server":

For a (not so) small fee, of course.
