SAME Function

Standard Library function that tests if two variables are the same.

Usage

result = SAME(x, y)

Input Parameters

x—A variable.

y—A variable.

Returned Value

result—1 if two variables are the same (within keyword settings), 0 if not.

Note:

For Named Structures, the name is not tested, so {a,x:1} is same as {b,x:1}.

Keywords

NoType—If set, types of x and y are ignored. (FINDGEN(5) is same as INDGEN(5).)

NoDim—If set, the dimensions of the arrays are ignored. ([1,2,3,4] is the same as [[1,2],[3,4]] - same as SAME(a(*),b(*).)

NoVal—If set, values in arrays are ignored. ([1,2,3] is the same as [3,4,5].)

Tl—A tolerance on the comparison of numerical values.

Verbose—Setting this keyword will print a message to the PV‑WAVE window indicating what is different between the variables. If they are the same, no message is printed.

Examples

a = INDGEN(5)

b = DINDGEN(5)

; To test for exact match:

result = SAME(a, b)

PRINT, result

; To test for compatible sizes (replaces multiple SIZE calls):

result = SAME(a, b, /NoType, /NoVal)
