Hello,
I have a problem with FindRoot function.

1) At the beginning program solves system of linear equations from which creates a matrix "Gr".
2) Program substitutes the matrix elements.
3) Program counts a matrix "Glesser" on the basis of the matrixes "Gr", "Gammaf", "Gammas", "Ga".
4) Program tries to calculate FindRoot where the integrand expressions are elements of the matrix "Glesser".

And there I get errors:
   NIntegrate::inumr:
   NIntegrate::vars:
   FindRoot::nlnum:

Everything is in the notebook.

P.S. If U=0 everything is working, but integrand are more simpler.

Thx for   your time.
Kacper
