f=@(x)([5*x.*x.*x*sin(x)-exp(-x)]); y=fsolve(f,1);
总是出现Optimization terminated:first-order optimali这个错误
请matlab高手指教,

在f表达式中出现中括号是错误的,不知道是在你写程序的时候注意到了没?
fsolve(5*x.*x.*x*sin(x)-exp(-x)=1,x)
这样就可以了,祝好运
f(x)=x,x
x-2 ,X>=0 f(x)=f[f(x+5)],x分段函数f(x)= x-2 ,X>=0 f[f(x+5)],x
f(x)=x^2+x (x
f(X)=f(X+2)(x
f(x)=5x+3 f(x)=5x f(x)=x+2x+1 f(x)=5x+3 f(x)=5x f(x)=x+2x+1
f(x,-x)=x^2+2x,fx(x,-x)=5x+1,则fy(x,-x)=
设函数f(x)={x-3,(x≥10) f(f(x+5)),(x
设函数f(x)={x-3(x≥10) f(f(x+5))(x
若函数f(x)满足f(x)+2f(1/x)=5x+4/x,则f(x)=
f(x)=x|x|+2x (x
f(x)=｛x x≥0-x X
数学f(x)=x(x+1)(x+2)(x+3)(x+4)(x+5),求f'(0)=?
知函数f(x)={x-5x≥6,f(x+2)x
设f(x)={x+3,x>10,f(x+5),x
f(x)=x-5(X大于或等于6）,f(x+2)（x
设函数f(x)={x-5 x≥6 f(x+2) x
设f(x)={x+3,x>10,f(x+5),x
已知f(x)=x(x-1)(x-2)(x-3)(x-4)(x-5),则f‘(0)为
