Suppose I have the following MATLAB code.
syms a b c1 c2 c1 = a + b + pi*b c2 = a + b + 0.5*b
Then c1 gets evaluated to
a + b + pi*b and c2 to
a + (3*b)/2
However, I need MATLAB to calculate double-precision values for the coefficients for
b and not just symbolic expressions.
How do I do this? e.g. I want c1 to be evaluated as
a + 4.1416*b and c2 as
a + 1.5*b.
Also, suppose I am interested in doing arithmetic like c1*c2, c1*5, I would like the
b to evaluated as numbers.
How should I do this?
