Error Handling
I am very new to Sage, so apologies if the answer to this question is obvious.
I have a program, and at the final calculation, for T and E matrices calculated earlier, it needs to either calculate a matrix A such that T=AE
, or, if this returns an error message, calculate a matrix A such that p*T=AE
, where p is also calculated earlier.
In mock code, what I mean is:
Calculate E.solve_left(T)
If that returns an error:
A=E.solve_left(p*T)
else:
A=E.solve_left(T)
return A
But I don't know how to do that in real code.
