Full Description
Hands-On Introduction to LaVIEW for Scientists and Engineers provides a learn-by-doing approach to acquiring the computer-based skills used daily in experimental work. The book is not the typical manual-like presentation of LabVIEW. Rather, Hands-On Introduction to LabVIEW guides students through using this powerful laboratory tool to carry out interesting and relevant projects. Readers, who are assumed to have no prior computer programming or LabVIEW experience, begin writing meaningful programs in the first few pages. After learning through experience, readers can master the skills needed to carry out effective experiments.
