%% pescribing the elliptical slip distribution
% Define parameters
Lx = 100; % Length of the fault in x-direction
Nx = 512; % Number of points in x-direction
A = 1; % Maximum slip
a = 20; % Semi-major axis of the ellipse
x0 = Lx / 2; % x-coordinate of the center of the ellipse
% Create spatial grid
x = linspace(0, Lx, Nx);
% Define elliptical slip distribution along x-axis
slip_distribution = A * sqrt(1 - ((x - x0).^2 / a^2));
% Plot the slip distribution
figure
plot(x, slip_distribution, 'LineWidth', 2);
Warning: Imaginary parts of complex X and/or Y arguments ignored.

Shouldn't abs((x-x0)/a) < 1 ?
