Unable to perform assignment because the size of the left side is 1-by-200 and the size of the right side is 200-by-200.

And what exactly don't you understand about the error message ?
chi_evan_p(a,:)
is an object of size 1x200, the object returned from the call
sevan_p1( w(a),beta_evan,d)
has size 200x200. So you try to store an object of size 200x200 in an object of size 1x200. Dimension overflow.
