Product Reviews |
"DADiSP makes it possible for an engineer to hit the button to turn the program on at the end of the day, walk out of here, then come in the morning and find the work all done."
Rich Bond, Ford Heavy Truck
"DADiSP makes this kind of analysis very easy to do, so that I only have to worry about the science, not the programming."
Dr. Dan Davison, University of Houston |
