Using the function pcfitplane, I get an equation of a plane. In this case, it is [-0.097 -0.055 0.993]. How can I view it such that it overlaps with my point cloud ?

mdl = pcfitplane(...);

pcshow(ptCloud);

hold on

% The returned planeModel object has a plot method

plot(mdl);

Works good! Thank-you.

As an extension to the same problem, suppose I have PtCloud = [M X N X 3] matrix and an equation of a plane.

When I plot it using the plot function as usual, the plane looks very huge and my other data points which I have plot in 3D appear very minute. I don't want this. I want to plot it such it lies within the same range as my data in 3D. I have attached here an example data-set here and the equation of plane which has to be plot such that it overlaps with my data. Equation of plane: [0.0589 0.0111 0.9982]. I want to limit the size of my plane to my data.
