What is wrong?
>> T = @(x) 1/x; >> Q=integral(T,1,1000); Undefined function 'minus' for input arguments of type 'function_handle'.
Error in integral (line 4) N=(hmax-hmin)/0.0001;

Fun thing is I get a different error message:
Error using /
Matrix dimensions must agree.
Anyway, if you change your definition of T to
T=@(x) 1./x;
(note the dot!), it should work.

Thank you for the answer. You are right it has to be 1./x since the function has to handle arrays, but the main problem was quit different. Since I downloaded a set of MatLab-files within an application that used the name integral for a function of there own, integral.m, and the path was set so MatLab was looking there first. the new integral.m didn't work in the same way as the original integral.m of MatLab. Sorry for troubling you with a trivial problem. Best regard
