MATLAB: Shifting or sorting arrays with specific names

arraysnameshiftsort

I have a cell array of 1000*1 dimension with names on it. I want to shift my elements in such a way that the name starting with N and ending with CA goes to the end. How can I do it?

you could use arrayfun to extract the first and last two letters and then use strfind to locate the index at which the letters that you want and then use this index for the shifting

firstLetter = arrayfun(@(n) cellArrayNames{n}(1),1:size(cellArrayNames,1),'UniformOutput',0);
lastTwoLetters = arrayfun(@(n) cellArrayNames{n}(end-2:end),1:size(cellArrayNames,1),'UniformOutput',0);

Try this out

% identify the index of cell array "AllObjects" that contains "obj3"
idx = cellfun(@(x)isequal(x,obj3),AllObjects);   %logical index
% Remove that index from cell array
AllObjects(idx) = [];

Here is one way to do it:

c = {'(43)2'
     '(43)42(34)'
     '042123'};
substrings = regexp(c, '(?:\(\d+\))|\d', 'match');
result = cellfun(@(ss) arrayfun(@(n) [ss{1:n}], 1:numel(ss), 'UniformOutput', false), substrings, 'UniformOutput', false)
