Details:

In version 6.0.92 it is possible to pass 'end' as an argument to an anonymous
function:


f = @(x)x;
f(end)


It seems that 'f' is treated as one element array and 'end' in this case
returns 1. In Octave 5.2.0 it results in error.

Another example:


a = [4 5 6];
f = @(x)x;
a(f(end))


I think it should return 6 but it returns 4.
