How can I transform a point cloud back into an array?

Hello,
I created a point cloud out of an array and did a spatial transformation. Afterwards I filtered it. Here is the code:
tform = affine3d(T)
%Transformation
ptCloud = pointCloud(xyzPoints)
ptCloudIn = ptCloud
ptCloudOut = pctransform(ptCloudIn,tform)
roi = [-5,5;-5,5;0.01,1]
indices = findPointsInROI(ptCloudOut, roi);
ptCloudFiltered = select(ptCloudOut, indices);
When I want to do further things with the point cloud like deleting collumns, I get this error:
Array formation and parentheses-style indexing with objects of class 'pointCloud' is
not allowed.
How can I get a normal array out of the point cloud again?
Thank you for considering!
