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: Any help in the removal of these errors will be helpful. Everything is in the notebook.

If U=0 everything is working, but integrand are more simpler. Thx for your time. Kacper
