可以尝试用计算符号积分的 int 函数来求：syms D R rsyms xdf=(r.^2*acos((r-(D-(R-sqrt(R.^2-x.^2)))./r)-(r-(D-(R-sqrt(R.^2-x.^2))).*sqrt(r.^2-(r-(D-(R-sqrt(R.^2-x.^2))).^2))Q=int(df,x,0,2)但不幸的是，这样无法求出显式解来。如果用quad来...
31、现.设置的方法主要是几个.1.可以在windows 更改系统环境变量加上JAVA_OPTS=-Xms64m -Xmx512m2,如果用的tomcat,在windows下,可以在C:tomcat5.5.9bincatalina.bat 中加上:set JAVA_OPTS=-Xms64m -Xmx256m位置在: rem Guess CATALINA_HOME if not defined 这行的下面加合适.3.如果是linux系统Linux 在tom...

If the function is not defined, issue a warning and assign the output a value of 0. try a = notaFunction(5,6); catch ME if strcmp(ME.identifier,'MATLAB:UndefinedFunction') warning('Function is undefined. Assigning a value of 0.'); else rethrow(ME) end end Warning: Function is ...
分段函数绘图实际很简单,我给你举个例子吧。 分段函数如下: 对该函数绘图,首先应该利用matlab建一个函数ff(x),如下:function Y = ff(X) if X<0; Y=sin(X); elseif (X>=0 && X<10); Y=X.^2*cos(X)/100; else Y=sin(X).*X;
