Why am I getting "unsupported MATLAB function call" error is Matlab Coder when converting ODE functions?

While trying to convert the following test file:

function [ result ] = coder_odetest(start, finish)
    tspan = [start, finish];
    odeset('AbsTol',1e-10,'RelTol',1e-10);
    result = ode45(@f, tspan, 0.5);
end

function [x] = f(t,a)
    x=a;
end

the Code Generation Readiness Tool says that odeset and ode45 are not supported for code generation. However, the documentation:

Functions supported for code generation

says that these functions are supported for code generation. What is the problem here?

The problem was that I was using Matlab 2013b. The ODE functions are only supported in Matlab 2014b.
