Concatenate strings of a cell string
This equals CAT(2, C{:}) and SPRINTF('%s', C{:}), but is remarkably faster,
because the output is pre-allocated.
Str = CStr2String(CStr, Separator, Trail)
INPUT:
CStr: Cell string of any size. All not-empty cell elements must be
strings ([1 x N] CHAR vectors).
Separator: String, which is appended after each string of CStr.
This is thought to emulate: "sprintf(['%s', Sep], CStr{:})".
Optional, default: ''.
Trail: String or logical flag. For 'noTrail' or FALSE the trailing
separator is omitted. Optional, default: 'Trail'.
OUTPUT:
Str: [1 x M] CHAR vector, concatenated strings of the input.
EXAMPLES:
Write a cell string to a file:
Slow: fprintf(FID, '%s\n', CStr{:});
Fast: fwrite(FID, CStr2String(CStr, char(10)), 'uchar');
A comma-separated list;
CStr = {'First', 'Second', 'Third'});
Str = CStr2String(CStr, ', ', 'noTrail');
>> 'First, Second, Third'
