用quad求积分出错。

>> fun=inline('1/pi*0.97*3.7415*(10^8)*(x.^-5).*(2.7183^((1.43879*(10^4))/(x.*318).)-1)^-1')

fun =

Inline function:

fun(x) = 1/pi*0.97*3.7415*(10^8)*(x.^-5).*(2.7183^((1.43879*(10^4))/(x.*318).)-1)^-1

>> i=quad(fun,1,4)

??? Error using ==> inlineeval

Error in inline expression ==> 1/pi*0.97*3.7415*(10^8)*(x.^-5).*(2.7183^((1.43879*(10^4))/(x.*318).)-1)^-1

??? Error: Missing variable or function.

Error in ==> inline.subsref at 25

INLINE_OUT_ = inlineeval(INLINE_INPUTS_, INLINE_OBJ_.inputExpr, INLINE_OBJ_.expr);

Error in ==> quad at 62

y = f(x, varargin{:});

求大侠分析一下错在哪，谢谢啦

[rayer]

fun = @(x)1/pi*0.97*3.7415*(10^8)*(x.^-5).*(2.7183.^((1.43879*(10^4))./(x*318))-1).^-1

quad(fun,3.7,4.8)
