abs() is a function, so is sin().
a=-3;
b=abs(a);
c=sin(b);
or
sin(abs(-3))
Does this answer your question?

Notes:
- This only works for values returned by a function. Values that are calculated by a function but not returned are discarded unless special precautions are taken to preserve them.
- Combining the two calls in to one expression only works for the first output returned by a function. If a function returns multiple arguments and you need the additional outputs, then you must assign the result to variables (which you can then pass in to the next call.)

It's the same!

Maybe you should note that you need to make your function have an output argument.
function out=plus_one(in)
out=in+1;
function out=time_two(in)
out=2*in;
time_two(plus_one(1)) would yield 4.

@komal: You can read the code of e.g. MEAN: "edit mean.m". This is a function of a Matlab toolbox, but it is exactly the same mechanism as for user-defined functions. There are a lot of further good examples in the documentation and in the toolboxes.
