You can generate a file from a symbolic expression, in addition to a function handle. Specify the file name using thefileoption. Pass a character vector containing the file name or the path to the file. If you do not specify the path to the file,matlabFunctioncreates this file in the cu...
另外,int函数的第一个argin必须为syms类型,字符串、inline或者function handle都不行,以下3种调用方式全错 y2 = int('1/x', 1, 2); y3 = int(inline(1/x), 1, 2); y4 = int(@(x) 1/x, 1, 2); 结果: Undefined function 'int' for input arguments of type 'char'. Undefined function '...
利用symbolic方法求解方程的根 y=x∗sinx−x=0 >> syms x y = x*sin(x)-x; solve(y, x) ans = 0 pi/2 %或者 >> syms x solve(x*sin(x)-x) ans = 0 pi/2 2. cosx2−sinx2=0 >> syms x y = cos(x)^2-sin(x)^2; solve(y, x) ans = pi/4 ...
