Undefined Variable Function 'dlarray' although the DL Toolbox already installed

Hello, just recently trying to run the deep learning example on Matlab

From these page: https://www.mathworks.com/help/deeplearning/ref/dlarray.html?searchHighlight=dlarray&s_tid=doc_srchtitle

The syntax is simple:

rng default % For reproducibility
X = randn(3,5);
dlX = dlarray(X)

But i always get the error

Undefined function or variable 'dlarray'

Although the DL Toolbox already installed.

Uninstalled the DL Toolbox and reinstalled it wont help.

Any suggestion?

Thank you.

dlarray() was released in r2019b. It looks like you're using r2019a so you won't have access to that function, unfortunately.

My bad, it really is. Turns out the dlarray function only available since R2019b.

Thanks for the answer!
