I have just started learning how to solve definite integrals in matlab, and from the documentation, I picked up this example:
$\int^{\infty}_{0}(e^{-x^2} )dx$ but when I run it in my matlab, I get the error: "The expression to the left of the equals sign is not a valid target for an assignment." (the equals after x, and the second dot after 0 are underlined in red)
what is wrong with this? int() works for me when I try indefinite integrals, but not for this.

$\begingroup$Try to write:
syms x;
int(exp(-x^2),x,0,inf)The numerical value should be pi^(1/2)/2.
