This line of code is giving me the above error message

T = k^2 * Em(k) * (((k^2 - mean_nu) * E(k) + mean_nu *crack_aspect_ratio^2 * Gm * k)^-1 + (( k^2 + (Mean_nu * crack_aspect_ratio^2) ) * Em * (k) - Mean_nu * crack_aspect_ratio^2 * Gm * k)^-1)
Unrecognized function or variable 'k'.

Could someone please explain how to rectify the problem

You use Em(k) and Em * (k) in this line of code. Both cannot be correct, I guess.

Further check out whether E(k) is correct: E is treated as an array where the k-th element is referenced or as a function that is called with input argument 1.
