I easily plot teh following graph:

mesh(X,Y,F,'FaceColor','none');

No I need to bold, and change the color of just one of lines in the figure! For example in specific value xi=5, we have a plane cutting the surface and it is a line graph. I want to change the color of that specific contour line graph.

No exact solutions without your code and data.

One approach:

xv = -15:0.8:15;
yv = -10:0.8:10;
[X,Y] = ndgrid(xv, yv);
z = @(x,y) sin(x) + cos(y);
figure
mesh(X, Y, z(X,Y))
hold on
line_at_x = 5;                                                                                  % Define ‘x’ Value Of Line
plot3(line_at_x+zeros(size(yv)), yv, z(line_at_x+zeros(size(yv)), yv), '-r','LineWidth',2)      % Add Line To ‘mesh’ Plot
hold off
grid on
xlabel('X')
ylabel('Y')
