I am working on optimization, and I want to code a functions where I can sub() larger number of variables. for this, I generated a m functions with n variables. For example, let say 3 functions and 2 variables. num_var=2 x=symbols('x0:num_var') I generated this functions: f=[5*x0 + 4*x1 + 6, -4*x0 - 5*x1 - 6, -8*x0 - 10] and I have a point like: point=[-2.8,1.74] If I want to sub() in each function, what is the fastest way to do this? f[0].subs([(x[0],point[0]),(x[1],point[1])]) (this will give evaluation of first function in point) -- You received this message because you are subscribed to the Google Groups "sympy" group.
