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;

Ran in:
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))
