hi, I have a row matrix eg [30,0,0,0,0,10,0,0,0,0,30,30,30,0,0,0,0,0,10....] I have to consider first element i.e 30 (and label it by 'a') then I have to discard the elements between 30 and 10. then I have to consider first 10 (and label it by 'b'),again I want to discard the elements between the 10 and last 30 ( also want to discard the first two elements whose value is 30 and consider the last 30(and label it by 'c') ) I want to repeat the same steps for the entire row matrix whose size is 1x2000. I don't know how to do this. Please help me to write this matrix logic. Thanks in advance

Do not label them with different variables, just store them in a cell array

v=[30,0,0,0,0,10,0,0,0,0,30,30,30,0,0,0,0,0,10];
w=v~=0;
ii=strfind([0 w],[0 1]);
out=arrayfun(@(x) v(x),ii,'un',0);
celldisp(out)
