I have a cell array FINAL_OUTPUT < 50x1 cell > and another one called indexing as shown in the attached file. How can I append the indexing column inside the non-empty cells of FINAL_OUTPUT? In the end, I would like to have FINAL_OUTPUT{1,1} having size 3x3 FINAL_OUTPUT{2,1} having size < 1x3 > etc...and the empty cells of FINAL_OUTPUT should remain empty.

Here is a sample set. Thank you for your assistance. The idea is that the rows of indexing should be appended to the non-zero rows of FINAL_OUTPUT

check_not_empty.mat

these are the indices of FINAL_OUTPUT to which each row of indexing corresponds.

在 MATLAB Online 中打开

Using cellfun and num2cell and an anonymous function:

>> out = cellfun(@(F,I)[F,num2cell(I)], FINAL_OUTPUT(check_not_empty), indexing, 'UniformOutput',false);
>> out{1}
ans = 
    'A'    [       110]    [1]
    'B'    [       110]    [2]
    'C'    [2.8422e-14]    [3]
>> out{2}
ans = 
    'A'    [56.5000]    [1]
>> out{3}
ans = 
    'A'    [55]    [1]
    'B'    [55]    [2]
    'C'    [55]    [3]
