Please help find the error in my face recognition using eigenvectors and eigenvalues!!!!

I copied this code from a textbook but I am still getting this error:

Undefined function or variable 'proj_new'.

Error in bigdata (line 50) E=norm(proj_B-proj_new)/norm(proj_B);

I have attached my code. Any advice will be helpful!

Either the textbook was wrong or you copied it incorrectly or you did not copy enough of it.

We do not know which textbook you are using, and we probably do not have a copy of the textbook. If the textbook is in electronic form you should search it to find proj_new
