Hello,
 
> How can we plot 3D points by reading from a file the coordinates

I guess you have 3 columns in a text file,
with respectively x, y and z.

To read the file, you can use read, fscanfMat or csvRead
depending on the format (see the related help).

The plot can be performed with param3d.

You'll find a short example attached.

Hope this helps
