Hi,
I usually do as follow: first store the list produced by lsolve as L, then use a.subs(L) as the value of a. For a cleaner code you may wish to add a check that the result is indeed a numeric and no exception occured.
Best wishes.

Hi I stumbled across this incredibly useful library and I wanted to use the lsolve function. I was reading the tutorial pdf to figure out how to use it. So from lsolve i end up with an expression like:

{a==3,b==4}

I was wondering how I could get a value of the a and b symbols from this? I would ideally like to store them in an int to use in another library. I have been looking for an answer for a while so I would really appreciate if anyone knows? I could parse it like a string but Im assuming there is a better way?

Thank you for your time,
Zach
