Hey @Noob
It seems that you want to color the first curve along the "x-axis" in a 3D surface plot. Here is something you can try:
1. Plot the Surface: Use "surf(X, Y, Z)" to create your surface plot with the desired colormap.
2. Extract the Desired Curve: To get the curve along the "x-axis" (first row of Y), extract the first row of your matrices:
x_curve = X(1, :);
y_curve = Y(1, :);
z_curve = Z(1, :);
3. Overlay the Curve: Use "plot3" to overlay the extracted curve in black:
hold on;
plot3(x_curve, y_curve, z_curve, 'k', 'LineWidth', 2); % Black line with desired thickness
shading interp
hold off;
You can refer to the following MathWorks documentation for more information on "plot3" function:
