Using Datetiim to produce array of time points

I'm trying to use the Datetime function to produce an array of data points to use as input to an array of impedance values to process and plot. I have entered 8 points for Year, Month, and Day. MATLAB claims this is what it wants, even while it denies the Datetime function and won't work. How can I get this data entered into numerical Year,Month, Day for plotting and analysis?
The datetime function is described here:

Thanks.

Look at the size of the variables Y, M, and D. One of these things is not like the others. Just because two arrays have the same number of elements or the same length does not mean they have the same size. Transpose your D variable and it will work.
