MATLAB: Find row and collumnumber in matrix.

cell arraysdifferent lengthfindlogical indexingMATLAB

Hi all,

I have got a cell array with cells of different lengths: A=[0,0,0,0],[0],[0],[1],[0] and I would like to know the location of 1. When I use

c = find([a{:}] == 1); I get 7, instead of 4. How can I find the location of the 1?

Thanks, Daan

This finds cells that contain a 1, maybe amongst other numbers:

 find(cell2mat(cellfun(@(x) (any(x==1)), C, 'UniformOutput', false)))

This looks for a single 1

 find(cell2mat(cellfun(@(x) (isequal(x,1)), C, 'UniformOutput', false)))

Never name a variable table because it will shadow the inbuilt function.

[row,column] = find(strcmp(TAble,'Activity desc.'))
[row,column]=find(ismember(TAble,'Activity desc.')) % if you're using version prior to strcmp() was introduced
