[問題] 匿名函式跟 ezsurf已回收
板上的大大們，小弟不才
剛學matlab不久，今天在練習時
用匿名函式碰到的問題
懇請大大們幫忙，感恩~~
ex7_3.m
***************************************************
function ex7_3()
f=@(x,y) y^2-x^2+1;
ezsurf(f,[-3,3,-3,3]);axis tight;
xlabel('x-axis');ylabel('y-axis');
***************************************************
我這樣打之後會出現以下的警告：
Warning: Function failed to evaluate on array inputs; vectorizing the
function may speed up its evaluation and avoid the need to loop over
array elements.
> In specgraph\private\ezplotfeval at 59
In ezgraph3>ezeval at 623
In ezgraph3>surfplot at 550
In ezgraph3 at 49
In ezsurf at 65
In ex7_3 at 3
但如果我把變數 f 註解掉，然後把 ezsurf的f改成字串'y^2-x^2+1'後就不會出現了，
2個寫法畫出來的結果都一樣~~
