I created a program "QPIMAT" with Connectivy Kit, pasted the code and sent to calc, it works well with a test matrix, writing "qpimat()" directly, but I cannot see it listed in Catalog User (I've only QPI): why?
It's on Programs list...

It's technically a CAS function. Perhaps this is why it is not listed. In the CAS view, you can create functions; for example: f(x):=x^2. You can see that if all such functions were listed as programs, it can cause a lot of clutter. Perhaps this may change in the future... I have no idea.
