inline function with 3 variables

hello,

I'm trying to run this code but I don;t know how to write the function in a way that uses the values of h and t, then fx(a) and fx(b). can anyone please help

t = [5 6 7 8 9]
h= [2 3 4 5 6]

fx =inline('((2*pi.^2)./t)-(((9.81*2*pi)./x).*tanh((2*pi*h)./x))')



a = 1;

b = 10;
tol = 0.001;
fx(a)
fx(b)

You cannot do that with inline functions. Every name you mention in an inline function must either be a function call (like tanh or pi -- pi is a function), or else it is turned into a parameter that must be passed to the function at the time it is executed.

You should not use inline functions unless someone imposes a requirement on you that you cannot overrule. You should use anonymous functions instead. http://www.mathworks.com/help/matlab/math/parameterizing-functions.html

thank you. I ended up using anonymous function and that worked. only problem is now the function keeps running for much longer than i think it should so, some progress made and some to go.
