2 积分函数int & integral & quad int是Symbolic Math Toolbox的,而integral和quad属于MATLAB通用工具箱 2.1 不定积分 符号积分有个数值积分没有的功能:不定积分。显然,定积分算出来本身就是一个数,当然没有不定积分这一说法。 int(1/x) 结果: ans = log(x) 2.2 定积分 2.2.1 int 用int积分的代码如下:...
Symbolic Math Toolbox provides a set of functions for solving, plotting, and manipulating symbolic math equations. You can generate MATLAB functions, Simulink function block, and Simscape equations directly from symbolic expressions or you can share your
To find the indefinite integral, enter int(f) ans = x/2 - sin(2*x)/4 Indefinite Integrals of Multivariable Expressions If the expression depends on multiple symbolic variables, you can designate a variable of integration. If you do not specify any variable, MATLAB chooses a default variable ...

I know...I think that is my problem. However, I have no idea how to solve it. In the end, I really only want to know when B=0. Is there any easier way to do this? Do I need symbolics? I have a friend who is a bit better at Matlab than I am (read:he is very good) ...
