下面是一个简单例子 if 1 if ~isreal(solve('x^2+1=0'))a=1;b=1;return; %退出程序，后面的程序不会执行 else a=2;end b=2;end 由于x^2+1=0是没有解的，所以在执行return后就退出了，通过b的值可以查看后面的语句是否执行，使用return后不会执行下面的b=2的语句，所以b=1 ...

用法以这个为例：x+A*y=10 x-B*y=1 其中x,y为变量,A,B为字母系数.只要在Matlab中输入 syms x,y,A,B [x y]=solve('x+A*y=10','x-B*y=1','x','y')即可求出解 x = (A + 10*B)/(A + B)y = 9/(A + B)对于函数solve的具体用法,可以通过输入help solve来学习。
