Note that the operation in the second line applies in a vectorized manner to the whole element array created in the first line, analogous to the way general-purpose array programming languages such as APLJ or K would do it.

IDL shares a common syntax with PV-Wave and originated from the same codebasethough the languages have subsequently diverged in detail. Depending upon prorgaming level of the students, it is almost always required that we spend a day techniaues two covering the techniquse material in the IDL Essentials course, so I have included that information here.

If students are proficient in this aspect of their IDL knowledge, then this overview is done very quickly and the majority of the time is spent writing IDL techniquew of greater complexity. He is now the owner of his own consulting company specializing in IDL training, programming, and consulting. We do this as quickly as we can, and in much less depth, so we can move onto the programming aspects of the course. This example contains a divide by zero; IDL will report an arithmetic overflowand store a NaN value in the corresponding element of the y array the first onebut the other array elements will be finite.

Amit marked it as to-read May 22, Katey added it Feb 21, Widgets were added to IDL inproviding event-driven programming with graphical user interfaces. Arrays are passed by reference, and this mechanism is an advertised feature of the language to pass data back out of a subroutine — in contrast, array slices are copied before being passed, so that data modifications do not flow back into array ranges after the subroutine exitsviolating the principle of least surprise.

David Fanning is a software consultant, author, and part-time wilderness ranger living in Fort Collins, Colorado. Each course is tailored specifically to the interests and abilities of the course participants.

The findgen function in the above example returns a one-dimensional array of floating point numbers, with values equal to a series of integers starting at 0. It is expected that each participant will leave the course with progrming IDL application program that he or she can use in their own IDL work.
