Method on @sym: double (x) ¶

Convert symbolic to doubles.

Example:

x = sym(1) / 3
  ⇒ x = (sym) 1/3
double (x)
  ⇒ ans =  0.3333

Despite the name, this is one way to convert a complex sym to floating point:

z = sym(4i) - 3;
double (z)
  ⇒ ans = -3 + 4i

If conversion fails, you get an error:

syms x
double (x)
  -| ??? ... Cannot convert expression ...
