how to save different size of user groups in a cell array.

Error using vertcat

Dimensions of arrays being concatenated are not consistent.

Error in DNUA (line 73)

feasibleGroups = [feasibleGroups; groups_k];

To resolve this issue, you can store arrays of different sizes in a cell array without concatenating them.

Hi Shaifali,

I understand that you are looking to add groups of varying sizes to a cell array but are encountering the following error: “Error using vertcat: Dimensions of arrays being concatenated are not consistent.”

Below is a sample script that demonstrates how to add groups of different sizes to a cell array:

group1 = [1, 2, 3, 4]; % Group 1 with 4 users
group2 = [1, 2]; % Group 2 with 2 users
group3 = [1, 2, 3, 4, 5, 6]; % Group 3 with 6 users

% Adding each group to the cell array
userGroups{1} = group1;
userGroups{2} = group2;
userGroups{3} = group3;
% Dynamically adding user groups
newGroup = [4, 5, 3, 8];
userGroups{end + 1} = newGroup;
userGroups

userGroups = 1x4 cell array
    {[1 2 3 4]}    {[1 2]}    {[1 2 3 4 5 6]}    {[4 5 3 8]}

For more information related to cell array, please refer the following MATLAB documentation link: https://www.mathworks.com/help/matlab/cell-arrays.html

Hope this helps!
