This function calculates the standard deviation of all or a subset of the elements in the numeric src array.
- This function requires the enhanced NBC/NXC firmware.
|src||The source numeric array. |
|idx||The index of the start of the array subset to process. Pass NA to start with the first element. |
|len||The number of elements to include in the calculation. Pass NA to include the rest of the elements in the src array (from idx to the end of the array). |
- The standard deviation of len elements from the src numeric array (starting from idx).
- You cannot use NXC expressions with this function
