scatter not ploting matrix

So the documentation for scatter explicitly states it can accept matrix inputs for Y, however when I try to do this matlab rejects my input ("Error using scatter (line 78) X and Y must be evctors of the same length.").

Was this functionality introduced after R2019b, is the documentation wrong, or am I reading it wrong? I've repeatedly checked that my data matches in one dimension as noted in the documentation (X is a 1600x1 vector, Y is a 1600x10 matrix), so that's not the problem

Yes this functionality was just recently introduced in R2021a

The relevant section from the release notes reads:

Scatter Plots and Constant Lines: Create multiple scatter plots or constant lines at once

• The scatter, polarscatter, and swarmchart functions now accept the same combinations of matrices and vectors as the plot function does. As a result, you can visualize multiple data sets at once rather using the hold function between plotting commands.
