List of Routines

• ADD_ARRVAL Add an element to an array. If input array is undefined,
• ARRAY_INTERSECT Pick the common elements from two arrays. Duplicates are removed. The
• ARRAY_UNION Return the union of elements in two arrays. Duplicates are removed.
• ARRSCL Rescale the range of an array.
• BINARY_SEARCH Perform a binary search on arr, an input array, for the closest match
• CLOSE_MATCH this will find close matches between 2 sets of points (t1,s1)
• COMBINE_PTRLIST Combine a ptrarr, each containg pointers to list of the same types of
• DELVARX Make input variables undefined. Similar to intrinsic DELVAR, but
• DOC_METHOD Display the documentation for a method of an IDL class. This requires that
• FSHIFT Routine to shift an image by non-integer values
• GET_CONSECUTIVE Return indices for first/last pairs of consecutive integers.
• INTFUNC Make a cumulative integral function. Basically just tabulate
• KMAP this maps (xin,yin) to (xout,yout)
• KMAP_INV this find the inverse map for kx and ky (any order)
• MAKE_DEVAUC Dave Johnston's code. My Changes. E.S.S.
• MAKE_EXP make an array with values set to an ellitical exponential.
• MAKE_GAUSSIAN make an array with a gaussian in it
• MAKEGAUSS make an array with values set to a gaussian. Assumes center of
• MATCH_DUP Find the matching elements of two arrays of integers (arr1 and arr2),
• MATCH_MULTI Find the elements of an array of integers (arr2, which may contain
• MFACT find the factorial of each element in an array.
• MKSTR Make a string of a give length. Default is an empty string, but a value can be sent. Can optionally make string arrays.
• NTOSTR Convert a number to a string. Cuts off white spaces.
• PARSE_CONFIG Parse simple 2 column "option value" config file. Each is read in as a
• PRO2HTML Convert an IDL .pro file into a pretty HTML document, with EMACS-like
• PROMPT_KBRD Prompt the user for an input key. Wrapper for get_kbrd() that only prompts
• PTIME print a time interval in a nice format if days,hours,minuties,seconds.
• REFORM_PTRLIST Take an array of pointers, each of which may point to arrays themselves,
• RND Round a number to the nearest decimal point. Similar to build-in round, but
• STRINGREP Get a string representation that can be used with execute() to create a
