Clear symbolic from an equation and make it mathematical function

Hi all,

I have an equaton of x, using syms x to create it.

However afterwards I want to clear the symbolic value and convert it to a mathematical function f(x), in order to represent it graphically for various x values.

I tried it manually by just doing copy paste, but the problem is that I get an error ",x" meaning I need again manually to fix it.

Is it possible to do it automatically?

thanks

example

syms x
f=(17*exp((281*x)/50000))/1000 + (4777*x*exp((281*x)/50000))/50000000

afterwards in order to put values (without symbolic values) it should be like that (using ".x"):

x=4.5:1:40.5;
g=(17*exp((281*x)/50000))/1000 + (4777*x.*exp((281*x)/50000))/50000000;

syms x
f=(17*exp((281*x)/50000))/1000 + (4777*x*exp((281*x)/50000))/50000000

f = 

ff = matlabFunction(f);

x=4.5:1:40.5;
plot(x, ff(x))

Thanks a lot, exactly what I needed!!
