Nikola, you probably don't have the Symbolic Math Toolbox installed/licensed. To check use

 ver

to list all installed toolboxes. In addition, try

 license('test','symbolic_toolbox')

to see if a license exists for the toolbox. The command returns a 1 if it exists, a 0 if it does not.

Symbolic mathlab toolbox isnt on "ver" list, but when i write license('test','symbolic_toolbox') matlab giver ans = 1... This mean that I have licence for symbolic toolbox but it isnt installed? Wher can I find installation? I tryed to google it but mathworks.com cant open dl page...

Answer 3

[Nikola]

I installed new mathlab with all toolboxes, cause i couldn't find symbolic math toolbox... It took 2 hours... Do you know where can I find specific toolbox when needed? Best regards
