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

It looks like that in 64 bits MATLAB, the symbolic math toolbox was deprived from the installation.
However, you must use 32 bits MATLAB 2009a, even your OS is 64 bits. However, the toolbox seems to be installed when I try the ver or pathtool command. The symbolic math commands are working in MATLAB 2009a perfectly. Type "help help" for help command options, such as help for methods. However, the toolbox seems to be installed. Use the Help browser Search tab to search the documentation, or 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. 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. If you absolutely have to work with symbolic variables and degrees, use sin and cos instead, and convert the degrees to radians manually. This problem may seem a bit weird please bear with me. Obviously, MATLAB complains that cosd doesn't accept symbolic variables.
