MATLAB: Create string from a cell array

Question

Hi,

I have a list of names in a 1 by n matrix. I would like to make them into one string (to generate file names, the end result of my program saves a graph to a file). The names are from varargin (which allows variable amount of inputs)

names=varargin;

I have tried using:

char(names)

This does give a character result, but over n rows. I want one string. Ideally, I would be able to seperate names with underscores, but I would settle for just a string (no spaces) of the names.

Any help would be great.

Answer 1

Simple and fast:

Str = sprintf('%s_', varargin{:});
Str(end) = [];

But if the cell string has a lot of elements, this can be imrpoved: Obviously SPRINTF does not preallocate the complete string at first. Then try: FEX: CStr2String.
