MATLAB: Remove row of cell array that contains 0.

Question

For example, I have a = [{0} {0} {0}; {1} {3} {4}; {0} {0} {0}]. I would like to remove the row that contains all of zero so that I can have the result a = [{1} {3} {4}]. I try this but it not work.

    a(all(a == 0, 2), :) = []

what I am missing? Thanks.

Answer 1

out = a(all(cellfun(@(x)x~=0,a),2),:);

OR

out = a(all(cell2mat(a) ~= 0,2),:);
