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 .

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. Webcontour (u,v,z,n)是画等值线. 其第四个参数是控制等值线的值的. 如果n是一个标量，那么解释为等值线的条数例如. contour (u,v,z,20)那么它会根据数据的范围画出20条等值线. 如果n是一个向量，那么解释为需要等值线的值，例如. contour (u,v,z, [1 2 3 4])会画出z=1,2,3,4四个值 ...

WebDescription. example. contourf (Z) creates a filled contour plot containing the isolines of matrix Z, where Z contains height values on the x - y plane. MATLAB ® automatically selects the contour lines to display. The column and row indices of Z are the x and y coordinates in the plane, respectively. contourf (X,Y,Z) specifies the x and y ... WebPlot the gradient and contours of the function z = x e - x 2 - y 2. Use the quiver function to plot the gradient and the contour function to plot the contours. First, create a grid of x- and y- values that are equally spaced. Use them to calculate z. Then, find the gradient of z by specifying the spacing between points.
