Determine amount of items in Dataset

Hello, I am trying to write a simple script that removes all but the final "item" in a Dataset. Not sure if this would be called an element, so it's "item" in quotes. Attached is an image of a Dataset with 9+ of these items. When I try numel or size, I simply get "1". How do I find the number of items? Thanks in advance!

Hi Cory,
I understand that you are trying to find the number of elements in a dataset array, say A, and numel(A) returns 1. To find the number of elements, n, in the dataset array A, use prod(size(A)) or numel(A,':',':').
However, the MATLAB “table” data type is recommended to work with heterogenous data instead of the “dataset” data type.
