I have a 1801 x 20 data matrix where one column is one set of data. I need to calculate the log diff and I I actually wanted to clear each column from the zeros, but each column has a different amount of zeros within the data (which is not possible in a matrix). I did this so far:
p3=num2cell(p2) ;
p3(p3==0)=[];
or:
p3(cellfun(@(p3==0)=[];
But both didnt work.

result=cell(1,20);
for i=1:20
data=p2(:,i);
data(data==0)=[];
result{i}=data;
end
result
The result is a cell array, whose individual elements having coloum of the p2 martix without zero. Hence individual cell elements will have different length after zero deletion.

p2 = [1, 2; 0, 1]
p3 = num2cell(p2, 1);
Wanted = cellfun(@nonzeros, p3, 'un', 0)
