I got this this error when I run the program (Error while parsing expression)

I am using a function with different inputs but I got this error

Error while parsing expression: (((u(1))–(cax*(u(2))*(u(2)))–(jr*(u(5))*(u(3)))–((iz-iy)*(u(3))*(u(4))))/(ix)) in 'Final_Modelling_Sub/Quadcopter System Dynamics/Translational & Rotational Dynamics/Phidd Equation1' token "" was found, whereas ")" was expected

Answer 1

(((u(1))–(cax*(u(2))*(u(2)))–(jr*(u(5))*(u(3)))–((iz-iy)*(u(3))*(u(4))))/(ix))

That code is using unicode U+2013 "EN DASH" instead of U+002D "hyphen-minus" which is the - character

so what is the correct code

I got confused

[Mohammed AL-hadi]

same thing in this code I got error

(((cos(u(2))*cos(u(4))*sin(u(3)))+(sin(u(2))*(sin(u(4)))*(u(1)))-(cdx*(u(5))))/(m)

[Walter Roberson]

S = '(((cos(u(2))*cos(u(4))*sin(u(3)))+(sin(u(2))*(sin(u(4)))*(u(1)))-(cdx*(u(5))))/(m)'

S = '(((cos(u(2))*cos(u(4))*sin(u(3)))+(sin(u(2))*(sin(u(4)))*(u(1)))-(cdx*(u(5))))/(m)'

%    123   4 5 43    4 5 43    4 5 432 3   4 5 43 4   5 6 543 4 5 432 3    4 5 4321 2 1
sum(S == '(')

ans = 21

sum(S == ')')

ans = 20

21 open brackets, 20 closing brackets.

The numbers above are the number of bracket levels in effect "after" the character above has been executed. You can see that you get back to 1, but you should be getting back to 0 instead.
