I want to calculate the integral of the following function usingintin MATLAB. I tried the following way, but it always shows the errorInput arguments must be 'double': syms x int(exp(x) .*1000.* square(1000.* (x-1))) or syms x int(exp(x) *1000* square(1000* (x-1)), x,-...

See this link for how to correctly declare a function in MATLAB. Put this in a separate file named "your_function_name.m" function result = your_function_name(x, matrix) result = ((2*matrix)^(-1/2))*(x'); Then you can call your function like this: x = [x1 x2]; ...
Inline function: f(a,b,c,x) = a * x^2 + b * x + c ans = 6 但MATLAB官方已经申明在后续的版本中inline会被移除,取而代之的是匿名函数(Anonymous Functions)。之所以有必要搞清楚这个新东西,是因为MATLAB提供的很多其它函数的argin只能为function handle,比如integral, fzero, and fminbnd函数。

你的程序中有判断两个符号量大小的代码,但符号类型(sym)是不能比较大小的。gt是大于号的函数形式,也就是说,gt(a,b)与a>b是相同的。
其实很好理解啊。当你执行求积分函数后 F3变成了sym符号类型,这种类型是不能参与逻辑判断的。所以你应该改成F3=double(abs(F1-F2));
