Bug report for Octave 3.0.1 configured for i486-pc-linux-gnu
Description:
-----------
Octave gives the error that a function is undefined when trying to
create an anonymous function in a function
that has been called via an anonymous function handle. I am using Octave
3.0.1-6ubuntu1 on Ubuntu 8.10.
Repeat-By:
---------
function x = test
b = 1;
myfunc = @(a) myadd (a, b);
myfunc(2) % This works
[t, x] = ode45(@compute_rate, [0,10], [1.0]);
end
function dx = compute_rate(x)
b = x/2;
myfunc = @(a) myadd (a, b); % This doesn't
dx = myfunc(x/2);
end
function c = myadd (a, b)
c = a + b;
end
Output:
error: `myadd' undefined near line 11 column 19
error: called from `?unknown?'
error: evaluating assignment expression near line 12, column 8
error: called from `test:compute_rate' in file
`/home/adam/summerproject/models/test.m'
