For R2019b and older, the activation process will begin after installation.If prompted, opt to skip installation of any existing products. During installation, you may be prompted to overwrite any existing products.If you installed MATLAB somewhere other than the default folder, you will need to select the folder where MATLAB is installed when prompted for the MATLAB installation location. The MathWorks installer will install new toolboxes in the default MATLAB installation folder.MATLAB must be closed in order to run the installer.R2020a Update 2 Installation Files can not be used to install a toolbox to R2020a Update 3 MATLAB. If installing the toolboxes offline, the installation files must match the update version of MATLAB, e.g.you cannot install a toolbox for MATLAB R2014b into MATLAB R2015a. Toolboxes must match the release of MATLAB they are installed into, e.g.I'm not working on a student license either.Before running the MathWorks installer to install an additional toolbox, please keep in mind: I also realised that the documentation is always available when I take Help -> Product Help from the menu-bar, though it is not available in the function browser even after I try the sample code.ĮDIT-II > license('checkout','Symbolic_Toolbox') I'm not sure if this problem is just for this particular toolbox or not, but the other toolboxes I use at least seem to work fine. Some of them seem to blame it on MATLAB hashing the tollbox incorrectly, so I tried the rehash toolbox command as well, but had no luck. I found a few instances of other users facing similar problems on the Mathworks portal, but none of them seemed to provide any concrete solutions. However, the problem again arises when I close and reopen MATLAB. The code works fine and on trying the help command again, they seem to work fine as well. Moreover, when I try some simple code such as: > syms k x However, the toolbox seems to be installed when I try the ver or pathtool command. Type "help help" for help command options, such as help for methods. Use the Help browser Search tab to search the documentation, or When I try to access any function in the 'Symbolic Math Toolbox' in MATLAB, such as help ztrans or help laplace, I get the following kind of message ztrans not found. This problem may seem a bit weird please bear with me.
