To solve the problem for an arbitrary number of matrices, you can use a loop in MATLAB. Here's an example code snippet that you can use:
% cell matrix containing matrices
cell{1} = [1 2 0; 0 1 0; 5 0 0];
cell{2} = [1 3 0; 0 4 0; 5 0 6];
num_matrices = numel(cell); % Get the number of matrices
% Initialize variables to store the indices of constant and variable elements
[row_constant, col_constant] = find(cell{1} ~= 0); % Start with non-zero elements of the first matrix
[row_var, col_var] = deal([]); % Empty arrays
% Loop through the remaining matrices
for i = 2:num_matrices
% Find the indices of constant elements
[row, col] = find(cell{1} == cell{i} & cell{1} ~= 0)
% Update the indices of constant elements
[row_constant, col_constant] = intersect(row_constant, row, 'rows', 'stable')
% Find the indices of variable elements
[row, col] = find(cell{1} ~= cell{i} & cell{1} ~= 0 & cell{i} ~= 0)
% Update the indices of variable elements
[row_var, col_var] = unique([row_var; row], 'rows', 'stable')
end
