Hi I have a problem with a matrix calculation. This code doesn't work because I can't explain to the code that the part that is elevated at the cube is a number and not a vector. How could I do ??? Regards
function F=System11(x)
m=5;
n=6;
g=m*n;
pc=(1:1:m);
pr=(m+1):m:((m*(n-1))+1);
ur=(2*m:m:(m*n));
uc=((m*(n-1))+2):1:((m*n)-1);
F=zeros(2*g,1);
%%%%
for p=2:1:(n-1)
cc=(2+(m*(p-1))):1:(m*p-1);
F(cc,1)=x(cc)-(x(g+cc,1))^3;
end
F(pc,1)=x(pc)-(x(g+pc))^3;
F(pr,1)=x(pr)-(x(g+pr))^3;
F(ur,1)=x(ur)-(x(g+ur))^3;
F(uc,1)=x(uc)-(x(g+uc))^3;
%%%%
for p=2:1:(n-1)
cc=(2+(m*(p-1))):1:(m*p-1);
F(g+cc,1)=x(g+cc)-6;
end
F(g+pc,1)=x(g+pc)-1;
F(g+pr,1)=x(g+pr)-2;
F(g+ur,1)=x(g+ur)-3;
F(g+uc,1)=x(g+uc)-4;
end
SOLVER
m=5;
n=6;
g=n*m;
%Initial Condition
KI=ones(g,1);
TI=ones(g,1);
iniz = [KI; TI];
options=optimset('Display','iter');
[x,fval,exitflag,output,JAC] = fsolve(@System11,iniz,options);

A stab here ... There is a difference between x^3 and x.^3, just like there is a difference between x.*y and x*y.
