Hello
The H function works. the other two evaluations I can not solve the problem.
function val = H(z)
x=z(:,1);
y=z(:,2);
val=(1.25*y-sqrt(abs(x))).^2+x.^2-1;
endfunction;
function Sys=g(x)
gx=x(:,1);
gy=x(:,2);
g1=2*gx-(gx *(1.25*gy-sqrt(abs(gx))))/abs(gx).^(3/2);
g2=2.5*(1.25*gy-sqrt(abs(gx)));
Sys(:,1)=g1;
Sys(:,2)=g2;
endfunction
r=[3 1;4 2;3 5;8 2]
disp(H(r),"H");
H
8.232373
15.25
28.411865
63.107864
V=g(r');
disp(V,"g");
J = diffcode_jacobian(H,r);
disp(J, "Jacobian");

*Inconsistent row/column dimensions.
