Define a symbolic functionf(x)=1/(x−1)that has a pole atx=1. symsxf(x) = 1/(x-1) f(x) = 1x−1 Compute the definite integral of this function fromx=0tox=2. Since the integration interval includes the pole, the result is not defined. ...
If your variable of integration is y, and m and T are to remain symbolic (no definite value given for them before the integration), then you will have trouble finding an analytic integral. You effectively have a y^m term as part of f, and the integral of that part can look very diff...

1、Calculate the integral of a symbolic function: z=\int_{}^{}ydx=\int_{}^{}x^{2}e^{x}dx,z(0)=0 示例代码: syms x; y = x ^ 2 * exp(x); z = int(y)%Definite and indefinite integrals(定积分与不定积分) z = z - subs(z,x,0)%当z(0)=0时,x用0来取代, 输出结果:...
integral = polyint(c); a = polyval(integral, 2) - polyval(integral, 1); display('Area: '), disp(double(a)); Octave执行代码并返回以下结果 - Area: 5.7500 可以使用Octave提供的quad()函数给出替代解决方案,如下所示 - pkg load symbolic ...

I'm pretty new to symbolic functions andsymsvariables in MATLAB, why is MATLAB rejecting this code? The similar code that I tried that worked was: syms f(x); syms y; f(x) = (x^2) + y; integral = int(f, x, [03]);disp(integral); ...
对于积分: int(S,v) is the indefinite integral of S with respect to v. v is a scalar SYM. int(S,a,b) is the definite integral of S with respect to its symbolic variable from a to b. a and b are each double or symbolic scalars. The integration interval can also be specified usin...
I know the symbolic package is working, because the example code returns the correct definite integral. You can useevalin order to "evaluate" (duh) the integral. E.g. with your code above, I get: octave:9> eval( convolution )ans= (sym) ...
