How can i solve the error "Reference to non-existent field 'xShape'. Error in finDiffEvalAndChkErr Error in finitedifferences'"

2 views (last 30 days)
c = -1; % define parameter first
x = fsolve(@(x) myfun(x,c),[-5;-5])
function F = myfun(x,c)
F = [ 2*x(1) - x(2) - exp(c*x(1))
-x(1) + 2*x(2) - exp(c*x(2))];
Reference to non-existent field 'xShape'.

Hi, as my test, if c>0.367879, there is no solution for your equations.
