You cannot 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.
For example, if you have MATLAB R2018a installed but some of your toolboxes are only eligible for R2017b then you will not be able to utilize the toolboxes on R2018a. Should you be interested in utilizing your toolboxes for the latest release, please look into renewing maintenance for the other toolboxes as well. R2010b and Older
Sometimes a toolbox upgrade becomes available between MATLAB releases (this is known as a "plus" release, as in R2009a+). In such cases, there will be two toolbox versions available for the same toolbox release, and both will be compatible with the MATLAB release.
Some MATLAB versions have Service Pack releases (R2010bSP1 for example). You cannot mix products of Service Pack releases with non-SP releases (or an earlier Service Pack release). For example, you cannot mix R2010b MATLAB with R2010bSP1 toolboxes. If you accidentally install these versions together, it is recommended that you uninstall and reinstall MATLAB.
NOTE: This is true for both the Professional Version and the Student Version
