Hello everyone,

I want to change the view of my surface plot {

} from

to a specific direction {

}

i.e,

azimuth angle (ϕ)=?

; →

elevation angle

Hence, i want to view the surface from

to a direction (

)

so, how can I perform it? please help...

I have used the surfl() function to plot my 3d surface {

}

My Code is as follows:

x=-6:0.01:6;
y=x;
[xx yy]=meshgrid(x,y);
zz=xx.^2 + yy.^2;
surfl(xx,yy,zz);
colormap(gray)    % change color map
shading interp    % interpolate colors across lines and faces
xlabel('x-axis ->')
ylabel('y-axis ->')
zlabel('f(x,y) ->')
title('f(x,y)= x^2 + y^2')

Use campos function

 i%f true
    % code
  %end
campos([4 4 0])

x y z are locations along x y z directions of the graph. See more info in the link below https://in.mathworks.com/help/matlab/ref/campos.html

You have two options.

You can use view, campos by providing the viewing point input coordinates.
You can do it manually, you have a rotation icon in the plot. You can click on it and adjuxt to your required view point.
