Hi Antonio,
I understand that you would like to plot a horizontal line when you pass the function handle to "fimplicit".
The "fimplicit" function assumes that the first variable in function handle corresponds to the x-axis, and the second variable corresponds to the y-axis. To achieve the desired result one approach can be swapping the order of the variables in the function handle.
Refer to the code snippets below: the first snippet uses y as the first variable and x as the second, while the second snippet has x as the first variable and y as the second.
% Define a function handle with y as the first variable and x as the second
my_function = @(y, x) y;
% Plot the function using fimplicit
fimplicit(my_function);
% Add labels and title for clarity
xlabel('x-axis');
ylabel('y-axis');
title('Desired Horizontal Line');
% Define a function handle with x as the first variable and y as the second
my_function_swapped = @(x, y) y;
% Plot the function using fimplicit
fimplicit(my_function_swapped);
% Add labels and title for clarity
xlabel('x-axis');
ylabel('y-axis');
title('Desired Horizontal Line (Swapped Variables)');
You can refer to below MathWorks documentation to know more about "fimplicit":
Hope this helps!
