Hands-On Introduction to LabVIEW for Scientists and Engineers, Third Edition, explores practical programming solutions for carrying out interesting and relevant projects. Readers--who are assumed to have no prior computer programming or LabVIEW background--will begin writing meaningful programs in the first few pages.
John Essick is Professor of Physics at Reed College. Since 1993, he has taught computer-based experimentation using LabVIEW as part of Reed's junior-level Advanced Laboratory and used LabVIEW to carry out many research projects.
