It shows that The expression: (1/(75.31*u(4)+167.36*u(5)+217.57*u(6)+334.37*u(7))*(0.84*(u(3)-u(2))+41840*exp(20.9057-(10000/(u(2)+275.15)))*x*(3)*u(5)+25105*exp(38.9057-(17000/(u(2)+273.15)))*u(4)*u(6))) has a syntax error. I don't know why it is wrong. Can someone help me? This is my first order equations
(1/(75.31*x(3)+167.36*x(4)+217.57*x(5)+334.37*x(6))*(0.84*(x(2)-x(1))+41840*exp(20.9057-(10000/(x(1)+275.15)))*x*(3)*x(4)+25105*exp(38.9057-(17000/(x(1)+273.15)))*x(3)*x(5)))
(1.6/200)*(u(1)-x(2))-(0.42*2)/(200*4.2)*(x(2)-x(1))-(0.084*4)/(200*4.2)*(x(2)-17)
-exp(20.9057-(10000/(x(1)+273.15)))*x(3)*x(4)-exp(38.9057-(17000/(x(1)+273.15)))*x(3)*x(5)
-exp(20.9057-(10000/(x(1)+273.15)))*x(3)*x(4)
exp(20.9057-(10000/(x(1)+273.15)))*x(3)*x(4)-exp(38.9057-(17000/(x(1)+273.15)))*x(3)*x(5)
exp(38.9057-(17000/(x(1)+273.15)))*x(3)*x(5)

Define a set of example value for u(1) to u(7) in MATLAB, copy and past your expression picece by piece in small parts and execute it in MATLAB, find which part causing the problem.
