SYMCAT is a capacity that gives an image list to indicating various plotting images.

IDL (Interactive Data Language) is a total processing condition for the intuitive investigation and perception of information. IDL coordinates an effective, arrayoriented dialect with various numerical investigation and graphical show procedures.

Programming in IDL is an efficient contrasting option to programming in FORTRAN or C—utilizing IDL, undertakings which require days or long stretches of programming with conventional dialects can be expert in hours. Clients can investigate information intuitively utilizing IDL charges and afterward make finish applications by composing IDL programs.
