I'm just getting started with Sage and therefore my question may sound really stupid (and nevertheless I couldn't find an answer here).
I have a matrix with both symbolic entries and numerical values, let's say:
a,b=var('a,b')
M=matrix([[1,a], [0,b]])
Now I want do assign a value to a:
a=0
However if I print M to the screen it still says a in the matrix and not 0.
You can clearly see that I'm really not used to Sage, so what's the problem here?
What should I do if I want to assign a fixed value to a variable which is also used in the calculations where this variable appears?
Thank's for the answers, I know this will sound highly trivial for you!
