MATLAB: Width of the plot

width

how do i estimate the width variations in this figure. I want to determine the variation in width along the major axis. Thanks

You can find intersection between data and perpendicular line

You can rotate data and find intersection

Use polyxpoly or intersections

MATLAB: Angle between two planes on the X=0, Y=0 and Z=0 planes

Hard to answer, because it's unclear (to me) what it is you're trying to compute. Your 2 given planes, with normals N1 and N2, intersect the XY plane in 2 lines. Is it the angle between these lines that you want? If so, that angle is,

      Nxy=[0 0 1]; %unit normal to XY plane
      N1=N1/norm(N1); %make sure all normals are unit vectors
      N2=N2/norm(N2);
      Angle_XY=acosd(dot(cross(N1,Nxy), cross(N2,Nxy))); %the result

Same sort of thing for the XZ and YZ planes.
