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 rows. For a data matrix, this corresponds to the number of values of each data series in the data matrix, and for a signal series, the number of points of each signal in the signal series. For a scalar value, it always returns the value 1, and for a list, it returns the number of elements in the list.
If the argument is a list, then the function is executed for each element of the list and the result is also a list.
