Re: sympy version?

I just upgraded to ubuntu 20.04.3

I compiled Octave GNU Octave, version 7.0.91 3ca33008c4a9

And installed

control *| 3.4.0

symbolic *| 2.9.0

I get errors when running a program that I wrote and it worked before.

*******************

>> wheelsym1

Try "sympref reset" and repeat your command?

(consider filing an issue at https://github.com/cbm755/octsympy/issues )

Do I need a different sympy version?

Doug

you may have to use sympy 1.4
