The UL64INDGEN function returns an unsigned 64-bit integer array with the specified dimensions. Each element of the array is set to the value of its one-dimensional subscript. For example, U=UL64INDGEN(100) will create a 100-element, 64-bit unsigned integer array with the values 0, 1, ..., 99.
Syntax
Result = UL64INDGEN(D1 [, ..., D8] [, START=value])
Return Value
Returns an array of the specified dimensions where each element of the array is set to the value of its one-dimensional subscript.
Arguments
Di
Either an array or a series of scalar expressions specifying the dimensions of the result. If a single argument is specified, it can be either a scalar expression or an array of up to eight elements. If multiple arguments are specified, they must all be scalar expressions. Up to eight dimensions can be specified. If the dimension arguments are not integer values, IDL will convert them to integer values before creating the new array.
Keywords
START
Set the START keyword to an integer giving the value of the first element in the array. The default is 0. Setting this keyword is equivalent to adding a constant offset to each element of the result.
Thread Pool Keywords
This routine is written to make use of IDL’s thread pool, which can increase execution speed on systems with multiple CPUs. The values stored in the !CPU system variable control whether IDL uses the thread pool for a given computation. In addition, you can use the thread pool keywords TPOOL_MAX_ELTS, TPOOL_MIN_ELTS, and TPOOL_NOTHREAD to override the defaults established by !CPU for a single invocation of this routine. See Thread Pool Keywords for details.
