Define variable inputs for 'merge' function

Hello,

could you please help me with the next problem.

I'm trying to merge N financial time series objects by function newfts = merge(fts1, fts2, ..., ftsx). How may I define a variable inputs for that? Because, when I have 2 time seriesobjects it becomes:

newfts = merge(fts1, ft2);

When I have 3:

newfts = merge(fts1, fts2, fts3);

How to avoid of examination of all posible options?

ATTENTION! Please, don't suggest to use a cell array

v={fts1,fts2,...,ftsn}

and use

 function   newfts = merge(v)

It doesn't work.

It is strange, that you do not want us to post the best solution by using a cell array. Unfortunately you only claim, that "it does not work", but do not mention any details. Of course it works, when you add a little "{:}":

v = {fts1,fts2,...,ftsn}
newfts = merge(v{:})

Then merge() gets a comma-separated list exactly as if you call it as:

newfts = mergs(fts1, fts2, fts3);  % Or how many elements v contains

In addition using a cell is a much better idea than naming the variables "fts1, fts2, ...". Using fts{k} would be more convenient, see http://www.mathworks.com/matlabcentral/answers/57445-faq-how-can-i-create-variables-a1-a2-a10-in-a-loop.
