需要求解包的八度

Question

Where can I find the solve package for octave? I need to solve algebraic equations and ODEs. For example I've tried:

x = solve('x + 3 = 0') error: 'solve' undefined near line 1 column 5

Or:

퓧댬>> x =fsolve('x + 3 = 0') error: Invalid call to fsolve. Correct usage is:

-- Function File: fsolve (FCN, X0, OPTIONS) -- Function File: [X, FVEC, INFO, OUTPUT, FJAC] = fsolve (FCN, ...)

Additional help for built-in functions and operators is available in the online version of the manual. Use the command 'doc ' to search the manual index.

Help and information about Octave is also available on the WWW at http://www.octave.org and via the help@octave.org mailing list.

Thanks for the help.

Octave itself doesn't contain a CAS system (but you can solve ODEs, see help lsode). You can install a symbolic toolbox like octsympy .
