too many input arguments .

function qdot=chain(q) 
T = q(1); 
theta = q(2);
y= q(3) ; 
s=q(4) ; 
Tdot = tan(theta); 
thetadot = 1/T; 
ydot = tan(theta); 
sdot = sec(theta); 
qdot= [Tdot;thetadot;ydot;sdot]; 
end

this the code i am getting frequent error could anyone please find where iam doing mistake.

You should show how you are calling the function. Note that, this function takes only one input q which is a 1x2 array. It seems, you are giving more number of inputs.

q = [1 2] ;
qdot = chain(q)

qdot = 4×1

-2.1850 1.0000 -2.1850 -2.4030

function qdot=chain(q)                                                            
T = q(1); theta = q(2);             
Tdot = tan(theta);                                     
thetadot = 1/T;
ydot = tan(theta);
sdot = sec(theta);
qdot= [Tdot;thetadot;ydot;sdot];                       
end

Thanks for giving me the hint i have found where the problem is .

[Mohammed sohaib]

the problem was on the input side i have put too many input arguments.
