Functions that are capitalized not work in Prime 4

[SamuelTWilson]

why do the functions that are capitalized not work such as LU, SVD, Cholesky etc. in Prime 4

[DJNewman]

Hiya,
They definitely work in PTC Mathcad Prime 8, at least.

They even work in unpaid PTC Mathcad Express:

I know these functions should work the exact same way in Mathcad Prime 4 as well.

Could you maybe attach your worksheet?

I just fired up Prime 4 and the functions work OK (svd must be written in lower case letters!)

And as DJNewman already wrote, these functions work the same even if you have no paid for license (Prime Express).

So maybe you can be more specific about the problems you experience.

I attach my file so you may give it try (don't forget to let Prime recalculate it after loading).
