fimplicit3​が使えない場合の3変​数方程式の描き方を教​えてください。

R2015bを使用しているため、 syms Z Q1 Q2 eqn=N+2^0.5/2*(Q1+Q2)==235/3; の方程式をfimplicit3を用いて図を描くことができません。 他の方法での描き方を教えてください。

ezplot3() will work fine

>> syms N Q1 Q2 >> eqn=N+2^0.5/2*(Q1+Q2)==235/3; >> ezplot3(eqn) インデックスが行列の次元を超えています。

エラー: sym/ezplot3 (line 25) y = char(sym(varargin{2}));

となってしまいます。

Can you upload the question in latex form or your photo of the question?

[m17td024]

sorry for my late reply. this is the photo that has error.

[madhan ravi]

I mean whats N Q1 and Q2 , is there any datas for it or its an equation ? like x+y=z.. if so please upload photo of your question

[m17td024]

No,they are independent variable and don't have any datas. But I solved it now.I misunderstood the formula itself. Sorry for making you go to all this trouble.

[madhan ravi]

No problem glad that you solved it
