Can I use R2020a toolboxes on R2019b MATLAB?

Can I use R2020a toolboxes on R2019b version of MATLAB? In other words, are they compatible?

[Madhav Thakker]

It is not encouraged to mix the toolboxes of two different releases of MATLAB. The release of the toolbox must match with the release of MATLAB. This is required to ensure the full compatibility of each product with every other product within a release.

Hope this helps.

Note that if you have a license for the toolbox in R2020a then that entitles you to use the toolbox of any earlier release, in its corresponding version. Newer toolboxes generally rely on newer infrastructure than is available in older releases. For example graphics objects change their details and what is done in R2020a internals might not have corresponding properties in earlier releases.
