Create a symbolic polynomial expression from coefficients.
If x is not specified, the free variable is set to sym('x'). c
may be a vector of doubles or syms. It can also be a cell array vector.
x may be a symbolic expression or something that converts to one.
The coefficients correspond to decreasing exponent of the free variable.
Example:
x = sym ('x');
y = sym ('y');
poly2sym ([2 5])
⇒ (sym) 2⋅x + 5
poly2sym ({2*y 5 -3}, x)
⇒ (sym)
2
2⋅x ⋅y + 5⋅x - 3
