Hello, how can i find the root of a nonlinear equation using Simulink? Can i use the Newton Raphson Method? I have to find the variable E in this equation: M = E - e*sin(E) Thanks, Lucas. 댓글 수: 6 이전 댓글 4개 표시 ...
%函数functiony2=draw2(x)y2=sin(x)+x;end%在命令行输入fplot(@draw2,[-5,5]) ③——ezplot y3='x.^2*exp(-x.^2)';ezplot(y3) ④——两曲线 syms xy=log10(x+sqrt(1+x.^2));dy=diff(y,x);%求导函数,但x不能先定义为向量,所以用subs让x1作为一符号代替表达式y中的默认变量x1=-3:...
