Unable to perform assignment because the indices on the left side are not compatible with the size of the right side.

I have this code (data attached) and i receive this error: "Unable to perform assignment because the indices on the left side are not compatible with the size of the right side". I tougth the problem was related to NaN and i also tried to remove them (third rows of the code) but it still give me this error.

Can someone help me?

load ('sclerometrica_equotip_v1')
misure = [ID_stop L Nn Bn];
% misure(any(isnan(misure), 2), :) = [];

ID_stop1 = misure(:,1);
L1 = misure(:,2);
Nn1 = misure(:,3);
Bn1 = misure(:,4);

k = unique(ID_stop1);
for i = 1:numel(k)
    index = (ID_stop1 == k(i));
    N= Nn1(index); %battute nodi
    j = unique(N);
    for m = 1:numel(j) 
        index2 = (N == j(m));
        L_nodo = L1(index2);  
    end
end

the code works ok

the code works for me. In which line are you getting the error?

yes sorry, i don't know what happens, it works also to me but it doesn't give me what i expect. I want to save the results of L_nodo in a matrix or in a cell array. For a cell array i tried this one (see modify in the code below), but in the second loop it overwrite each time the results. So i need 20 cells and in each cell there should be 20 sub-cells. After that i need an histogram for each cell.

I really don't know how to do.

k = unique(ID_stop1);
result = cell(1, numel(k));
for i = 1:numel(k)
    index = (ID_stop1 == k(i));
    N= Nn1(index); %battute nodi
    j = unique(N);
    for m = 1:numel(j) 
        index2 = (N == j(m));
        L_nodo = L1(index2);
        result{m} = L_nodo; %<--modify
    end
end

Not sure I understand.I tried you run it with /without the commented line and all worked fine without errors.

have you cleared your workspace variables before running this code?

yes maybe the problem was this one.. thank you
