WebWhen scale is a positive number, the quiver3 function automatically adjusts the lengths of arrows so they do not overlap, then stretches them by a factor of scale.For example, a scale of 2 doubles the length of arrows, and a scale of 0.5 halves the length of arrows.. When scale is 'off' or 0, such as quiver3(X,Y,Z,U,V,W,'off'), then automatic scaling is disabled. bridgepay add ons

WebYou're right that MATLAB defines its RGB colours as double values from 0 to 1, but in order to get a true conversion you should just divide the integers by 255, rather than copy them in as 0.xxx. Using 0.xxx , the "brightest" number you'll get is 0.255, which is still about one quarter as bright as the true brightest value of 1 . WebOnly applies to contour.
