in [Matlab]

From: Nilesh on 20 Jul 2010 09:50 I have been working on string . i got into a small problem.the problem is here as under here 's' is a structure ------ str = 'name' name s(1).(str) %works ------- str = fields1(1) %fields1 = fieldnames(s) 'name' s(1).(str) % does not work . here when i assign directly the str with required string , it contains no quotes.But if assign the str using the fields1 array the output is with quote but i dont want the quotes as its causing me problem of not able to access the element od the structure.Is ther anyway to solve this so that i can access the structure elements using the fieldnames array. Thanks, NILESH

They are NOT 'char arrays' -- they are 'cell arrays', and to extract the _contents_ of a cell from a cell array rather than the cell itself, use curly brace indexing. fields1{1} -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com
