Hallo

Wat voer ik verkeerd in bij matlab ?

clear all

close all

syms x

S = solve( '2*x=10','x')

Ik krijg de volgende foutmelding:

??? Undefined function or method 'syms' for input arguments of type 'char'.

Wanneer ik het volgende invoer:

S = solve( '2*x=10','x')

Ik krijg de volgende foutmelding:

??? Undefined function or method 'solve' for input arguments of type 'char'.

Ik heb matlab 7.4.0(R2007a)

Wie kan me helpen?

Lijkt erop dat je de symbolics toolbox niet hebt.

Tik eens in Matlab 'ver' en plaatst hier de output ervan.

>> 'ver'

ans =

ver

>> ver

Je hebt inderdaad de symbolic math toolbox niet. Je kunt dus niet symbolisch rekenen.

Hoi

Bedankt, had de hele DVD geinstalleerd, echter zit hij er niet tussen.
