matlab, given a cell array of strings "x = , write a function to sort the equations via toposort or similar? in matlab

main.m
function sortedEquations = sortEquationsTopologically(equations)
    % Create a directed graph to represent dependencies
    G = digraph();
    
    % Extract variables and dependencies from equations
    dependencies = cell(numel(equations), 1);
    variables = cell(numel(equations), 1);
    for i = 1:numel(equations)
        eq = equations{i};
        parts = strsplit(eq, '=');
        
        % Extract the variable and dependencies
        var = strtrim(parts{1});
        dep = strtrim(parts{2});
        
        % Store the variable and dependencies
        variables{i} = var;
        dependencies{i} = strsplit(dep, ',');
        
        % Add edges to the graph for dependencies
        if ~isempty(dependencies{i})
            for j = 1:numel(dependencies{i})
                G = addedge(G, dependencies{i}{j}, var);
            end
        end
    end
    
    % Perform topological sort
    order = toposort(G);
    
    % Reorder the equations based on the topological order
    sortedEquations = cell(numel(order), 1);
    for i = 1:numel(order)
        var = order{i};
        idx = find(strcmp(variables, var));
        sortedEquations{i} = equations{idx};
    end
end
