14 kwi 2010 · If you just wish to remove the zeros, leaving the non-zeros behind in a, then the very best solution is a(a==0) = []; This deletes the zero elements, using a logical indexing approach in MATLAB.
20 mar 2017 · To remove a single zero from each row of a matrix and rebuild the new matrix of nonzero entries, try the following code: a = [1 4 0 3; 0 1 5 5; 1 0 8 1; 5 4 4 0; 0 1 5 2] v = nonzeros(a');
6 cze 2012 · Note: the above code treats nan values the same as zero values, so for example the row [0 nan nan] would also be removed. If that is not acceptable, then b = a(any(a ~= 0,2),:);
31 maj 2012 · data ( all ( ~any ( data), 2 ), : ) = []; % removes all rows with all zero. data ( :, all ( ~any ( data ), 1 ) ) = []; % and columns. I mean the first line (% removes all rows with all zero) does not work!
10 cze 2018 · You can also use eerste_kijkmoment(eerste_kijkmoment~=0)=[]; to remove all non-zero elements and convert the matrix to a vector.
17 cze 2016 · It depends on what you are trying to end up with exactly but a good approach would be to set all zero values to NaN. NaNs wont show up in plots and you can use nanmean() or other functions which ignore NaNs to work with your matrix. This will also retain the shape of your matrix.
23 lip 2020 · How do I delete all the columns that have zeros with a for loop? I tried reducing the number of columns by one in every iteration but matlab shows me "index exceeds matrix dimentions".
