Summary

Hands-On Introduction to LabVIEW for Scientists and Engineerstakes a "learn-by-doing" approach to acquiring the computer-based skills used in daily experimental work. Ideal as either a course textbook or a self-study supplement, the book 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. Instructors using the text can easily choose the desired depth of coverage for their courses. New to the Second Edition * All chapters fully updated to latest version of LabVIEW * Color tear-outs of LabVIEW data types * "Quick Example" sections at the beginning of each chapter give concise introductions to the MathScript Node, Shift Register, and Case Structure * Solutions to odd-numbered back-of-the-chapter problems available on the companion website
