I have a data that plots a 3D figure. Now I am trying to rotate it from an point(origin) using

rotate(h,direction,alpha)

I read the defination on the mathworks and it said that the default origin point is the center of the plot box.However in my case, it is not a center point of the plot box. So how can I modify the origin to make sure I am able to rotate it around my desired point of origin?

You need to make a new 3d vector to define the origin and then add it as the fourth input parameter.

    hSurface = surf(peaks(20));
direction = [1 0 0];
origin = [0 0 0]; %set origin of axis of rotation to plot origin instead of the center of object
rotate(hSurface,direction,25,origin); %add the vector to the parameters
