title for the legend not the graph in matlab

To change the title of the legend in MATLAB, you can use the Title property of the Legend object. Here's an example:

main.m
% Create a plot
x = 1:10;
y = x.^2;
plot(x, y);

% Create the legend
legend('y = x^2');

% Change the title of the legend
legendTitle = 'My Legend Title';
legend('Title', legendTitle);

12 lines

In this example, the title of the legend is changed to 'My Legend Title'. You can modify legendTitle to set the desired title for your legend.
