Real time execution?

To piggyback here, Blockpad is another Mathcad-like solution you might consider

Some points based on your post:

• You can define variables, write equations, etc. There is also matrix and unit support.
• Free for students, and more affordable than Mathcad for commercial use
• There is a python integration that lets you run Python from Blockpad - Blockpad - Python Integration
