Storing multiple function outputs in an iterative loop

I have multiple variables (of different lengths) (input_1; input_2; etc ..input_i) and for each of them I would like to run my function that takes input_1 and returns output X_1, Y_1, Z_1 and saves it to the workspace (and then respectively taking input_i and returing X_i, Y_i, Z_i).

The input and output variables have different lengths for each index (i.e. input1 is different size than input2), so they can’t be stored in one matrix.

I tired running a for loop, but I don’t know how to save the output_i iteratively as separate variables (as they have different lengths) for each input_i in the function.

[X,Y,Z] = myfunction(input_variable);
%the function takes a 3d matrix and creates three 1d output vectors X, Y and Z of different lengths

%sample data (different size)
input_1=rand(100,4,3);
input_2=rand(50,3,1);
input_3=rand(10,2,5);

index_name = {'1', '2', ‘3’}; 

for i=1:length(index_name)

        AA = sprintf(‘input_%s’,index_name{i});
        input_variable = eval(AA);

        [X,Y,Z] = myfunction(input_variable);

%here I am not sure how to save output vectors Xi, Yi, Zi for each iteration, as the following code does not work:

        outputX = sprintf(‘X_%s’,index_name{i});
        eval([ outputX ' = X’ ]);

end

Please note that output vectors for each iteration have different lengths and can’t be saved in a matrix (i.e. outputs X_1, X_2, X_i has different lengths). I would really appreciate if somebody could tell me how to save them into workspace.

store them as cell arrays

[X{i},Y{i},Z{i}] = myfunction(input_variable);

x{1} could be NxM matrix

X{2} could be RxCxT matrix

X{3} could be even a string

So, really doesn't matter what are each element of cell arrays. They are independent of each other
