在 MATLAB Online 中打开

appearing near the run bottom as comment ,not in the command window.

this is code of the prog.

 function A = OSCaROrbit2ProjectionMatrix(theta_G,du,dv,u_off,v_off,SDD,SAD)

Nowhere in the above code is it asking the user for some input. Which line are you referring to, that which is %disp('Entering open_IMG');? If so, I think that the intent of this statement was just to say (at one time) that the software was now entering the function named open_IMG. Though since it is commented out (and there is no function called open_IMG), it no longer has any relevance. And the code doesn't seem to run anyway since pmhRotationMatrix is undefined.
