matlab
syms r p w z x;
a=10,b=100,c=0.2,m=6,v=4;
F=x/10
profr=(r*p-w)*(z+a-b*p)/(1-c)-(r*p-v)*int(F,x,0,z);
dprz=diff(profr,'z');
dprp=diff(profr,'p');
[zstar,pstar]=solve(dprz,dprp,'z','p')
profs=(w-m)*(zstar+a-b*pstar)/(1-c)+(1-r)*p*((zstar+a-b*pstar)/(1-c)-int(F,x,0,z));
dpsw=diff(profs,'w')
wtemp=solve(dpsw,'w')
profstmep=(wtemp-m)*(zstar+a-b*pstar)/(1-c)+(1-r)*p*((zstar+a-b*pstar)/(1-c)-int(F,x,0,z))
dpsr=diff(profs,'r')
rstar=solve(dpsr,'r')
wstar=subs(wtemp,'r',rstar)
para={[z],[p],[w],[r]};
parastar={[zstar],[pstar],[wstar],[rstar]};
profrstar=simple(subs(profr,para,parastar))
para={[w],[r]};
parastar={[wstar],[rsatr]};
profsstar=simple(subs(profr,para,parastar))
运行结果
Error using ==> solve
Error,(in solve) invalid arguments
Error in ==> sym.solve at 49
[varargout{1:max(1,nargout)}] = solve(S{:});

wtemp=solve(dpsw,'w')
你的这个语句是解不出来的,因为你的方程太复杂了!

MATLAB程序问题解一个方程组如下syms x y z t a b c d m s; f = x+z-a;g = (2 matlab >> syms x y z a b cy=16.7143*x^2-46.227*x+36.3129;z=0 matlab函数计算syms f o s z k D t m q T x;p=f-o-(s-o)*(1-erf(0.5* matlab t=linspace(0,pi/10,1000); >> syms x y z% >> th=[x*(1+ matlab 出错MATLAB问题 function vchu=tiji(ii,h)syms x y z m t h h matlab中 syms x y z; R =x^2+y^2；现在要用替换x变成R =z^2+y^2要怎么做? Matlab积分报错 syms x y dx dy z t;global e a c;x=a*cos(t);y=a*e* matlab 中,syms x 是不是相当于x=sym('x') matlab中 syms x; f=log(x) 为什么是错的? 集合A=｛x/x=9a+6b+5c,a,b,c属于Z｝B=｛x/x=3p+5q+6r,p,q,r属于Z｝在解题时,答案需 matlab程序：syms x y z; x=-50:0.1:50; y=-50:0.1:50; z=(4-2.1*x. 如何用Maple软件提取多项式 poly1 := A*x*z+B*x*r+C*y*z+D*y*r+E*x+F*y+G*z
