I am trying to determine how to write the solver code for this example problem. I want to determine the quantitiy s for a given value v such that the following holds true. Although I have provided an explicit integrand here, I am looking for the general code to evaluate this properly with any specified integrand. I just used this one because I am not looking for an analytical solution to this example.
v = 1;
fun = @(x) x.^x;
The error I get is as follows:
Undefined function or variable 'x'.
I am sure I am missing something silly. I would appreciate any help you can provide.
