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.)

I mean to say it is a user defined function not a matlab funvtion.

[Fangjun Jiang]

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.
