= __fgetArray =

== Syntax ==
{{double __fgetArray(int nr, int x, int y, int z)}}

== Arguments ==
:'''nr'''
::Number of the array. Values from 0 to 99 are accepted.
:'''x, y, z'''
::x, y, and z coordinates of a cell in the array. If you allocated a one-dimensional array, set y and z to zero. If you allocated a two-dimensional array, set z to zero.

== Return ==
Returns the double floating-point value that was stored at the specified coordinates in the array. ''Warning: If the specified coordinates lie outside the array, the plug-in may crash.''

== Description ==
This function lets you read a floating-point value from an array. This is a fast version of ((fgetArray)) without any error checking or memory checking. As it does not do any border checking, it may produce error messages or even crashes if not used properly.

== Example ==
See ((allocArray)) for an example of how to allocate arrays and use the similar ((fgetArray)) function.

== See Also ==
((__getArray)), ((__fputArray)), ((allocArray)), ((freeArray)), ((putArray)), ((getArrayDim)), ((copyArray))
