The syntax of the NumberOfElements function consists of the following parts:
Part |
Description |
|---|---|
DataSet |
The data set for which the number of elements is determined. All data structures are allowed. All data types are permitted. |
LoopList |
If DataSet is a list and this argument is set to True, then the function does not return the element count of this list, but a list with the element counts of the individual list elements of DataSet. Permitted data structures are scalar value. Supported data types are Boolean value. If this argument is omitted, it will be set to the default value False. |
Remarks
As the result the function returns a scalar value of data type 64-bit integer.
For a data series, signal or space curve, the function returns the number of values or points. For a data matrix or a signal series, it returns the number of columns. For a data matrix, this corresponds to the number of data series in the data matrix, and for a signal series, it corresponds to the number of signals in the signal series. For a list, the function returns the number of elements in the list. For a scalar value, the function always returns 1.
