- How long have you used PDL?
     since at least 2009

- What PDL version do you use?
   2.007

- Best thing(s) about PDL
   3D Matrix  Visualization 

- Worst thing(s) about PDL
     TriD's garbage collection 

- I would use PDL more (or at all) if only ...
    TriD dosen't seem to handle video garbage very well.
 I can do a large amount of dimensional analysis matrix work
      without visualizing it with TriD, and the Ram usage well be very 
efficient .
 however when I use TriD and try to visualize the work, I get hit with a Ram
     Usage problem, and cant get the same amount of work done. 

- Any suggestions for PDL development?
   Hacking the 3D projection (Ram Usage) Garbage collection for TriD would 
   make PDL  100% better.
Also a Module for working with Quantum Mechanics would be nice 
  as my inverse matrices are not producing the right out puts 
example
[1,2,3]
[2,4,5]
[3,5,6]

should equal 

[1,-3,2]
[-3,3,-1]
[2,-1,0]

however in 2.007 it equals 
 
 [         1        0.5 0.33333333]
 [       0.5       0.25        0.2]
 [0.33333333        0.2 0.16666667]
