Plot data from matrix with legend name

Dear colleagues,

how can I plot data from a matrix and have the legend entries in it automatically, too?

To make my question easier to understand I attached a code snippet:

1) What works:

Matrix = [a, A_2, 0];
%% Plot
figure
hold on
for i=1:size(Matrix,1)
    plot([0,Matrix(i,1)],[Matrix(i,2),Matrix(i,3)])
end

2) Waht I want to have:

Matrix = [a, A_2, 0, 'legend entry'];
%% Plot
figure
hold on
for i=1:size(Matrix,1)
    plot([0,Matrix(i,1)],[Matrix(i,2),Matrix(i,3)])
    legend(Matrix(i,4))
end

Can you please give me a hint?

Best regards

Felix

Cells are for that purpose, see help on cell

Matrix = {a, A_2, 0, 'legend entry'};

Matrix =

  1×4 cell array

To access matrix first complete cell

Matrix{1,1}

it will give you a

if you want the first element of a you can access it using

Matrix{1,1}(1)

Dear Muhammad,

thank you for your explanation and code. This works out good.

Do you happen to know how I can use the legend option properly?

If I use it in the "for loop" only one legend entry remains.

Best regards

Perhaps I add the code snippet to explain my problem in an easier way:

Matrix = {a, b, c, 'legend 1';...
          d, e, f, 'legend 2';...
          g, h, i, 'legend 3'};

%% Plot
figure
hold on
for i=1:size(Matrix,1)
    plot([0,Matrix{i,1}],[Matrix{i,2},Matrix{i,3}])
    legend(Matrix{i,4})
end
hold off
grid on

figure
hold on
for i=1:size(Matrix,1)
    plot([0,Matrix{i,1}],[Matrix{i,2},Matrix{i,3}])
end
legend(Matrix{:,4})
hold off
grid on

Thank you very much, Muhammad! ( I don't know why I didn't see this solution myself.)
