function [vecaz vecel] = smoothOperator(stru,chngt) %Show-off! You've finally nailed that bodies of rotation code down and %want to show it off to your family and friends. What you would like to %do is have MATLAB rotate the camera smoothly around your body of %rotation (or other plot) for added effect. You've already written a %function, swivelCamera, that takes in a vector of azimuths and a vector %of elevations that describe angles from which your plot should be %viewed. swivelCamera also takes in a duration in seconds that you %would like to pause between shots (delta t). What you need to do now %is write a function, smoothOperator, which will generate azimuth and %elevation vectors that will move the camera smoothly around your plot. %You have several angles which you would like to view your plot from, %and you would like to visit them at certain times. To keep track of %these angles and times you will use a structure with fields t, az, and

[num pos] = sort([stru.t]); %gets the numbers and positions of the values in the field t stru = stru(pos); %indexes only th random = ((stru(end).t-stru(1).t)./chngt)+1; time2 = linspace(stru(1).t,stru(end).t,random); vecaz = spline([stru.t],[stru.az],time2); vecel = spline([stru.t],[stru.el],time2); end...
