MATLAB: Error using function fplot

Question

When typing my code, I keep getting the error of invalid parameter from fplot. Not sure why it keeps coming up. How would I fix this?

Code:

syms x

f(x) = log(x)^4 * exp((-x)^3) * x^2;

val = int(f(x),x,[0,Inf]);

vpa(val)

X = [0.5 : 0.1 : 2.5]

fplot(@(x) f(x),X,'b')

Answer 1

You need to specify range with two numbers.

syms x
f(x) = log(x)^4 * exp((-x)^3) * x^2;
val = int(f(x),x,[0,Inf]);
fplot(@(x) f(x), [0.5 2.5],'b')
