Inserting the symbolic variable in atan results in an error. How can I resolve this error?

syms theta [1 6] matrix

syms x
t1 = T(theta(1,1),theta(1,2),theta(1,3),theta(1,4),theta(1,5),theta(1,6));
fk(1,1) = t1(1,4);
fk(2,1) = t1(2,4);
fk(3,1) = t1(3,4);
atan(t1(3,2)/t1(3,3))
err : Check for missing argument or incorrect argument data type in call to function 'atan'

To resolve the error you are facing, do the following:
  1. Check if t1(3,2) and t1(3,3) exists.
  2. Debug your code and check whether the output you get from "T" (which I assume to be a function) is as you expected.
I also tried passing symbolic variables into the "atan" function and didn't get any errors.
syms x y
t1 = x+4;
t2 = y-6;
atan(t1/t2)
ans = 
Unfortunately, I was unable to reproduce the issue at my end due to the missing function or variable "T". So, if these steps don't solve your issue, in order to better assist you, kindly share your function "T".
