    vector_of_x = as appropriate
vector_of_y = as appropriate
[X, Y] = meshgrid(vector_of_x, vector_of_y);
points = [X(:), Y(:), z(:)];
ptCloud = pointcloud(points);
    pointCloud is part of the Computer Vision Toolbox
    pointCloud() is a particular data type in MATLAB. If you do not have Computer Vision, then you cannot create the datatype, so it is not clear what you want to do? If you just want an array of three columns, X, Y, Z, and you are starting from a 2D array, then use the code I posted but stop after the assignment to points
