I'm trying to solve this system equations in matlab
syms y z i x=[29.6,29.4,34.4,35.1,34.3,36.1,31.6,32.9,31.5,28.3,37.1,28.4,27.3,33.1,31.3,33.1] n = 16 eqns = sym(zeros(1, 2 * n)); for i = 1:n a = 0; for j = 1:i a = a + exp(-((x(j) - y) / z)); end a = i/z - a/z; eqns(i) = a == 0; end for i = 1:n a = 0; for j = 1:i a = a + ((x(j) - y)/z^2) - ((x(i) - y)/z^2) * exp((-x(j) + y)/z); end a = -i/z + a; eqns(i + 16) = a == 0; end eqns solve(eqns, [y, z])
But it seems
solve can't solve this one.
Warning: Cannot find explicit solution. > In solve (line 316) In xx (line 24)
I tried to use fslove but by follow the tutorial at https://www.mathworks.com/help/optim/ug/fsolve.html?s_tid=gn_loc_drop
but when I tried to enter
function F = root2d(x) F(1) = exp(-exp(-(x(1)+x(2)))) - x(2)*(1+x(1)^2); F(2) = x(1)*cos(x(2)) + x(2)*sin(x(1)) - 0.5;
matlab throw error.
Can someone please help me?
P/S: Can this problem be solved with singular?I'm trying to solve this system equations in matlab
