Abstract
We present the diagrammatic technique for calculating the free energy of the matrix eigenvalue model (the model with arbitrary power by the Vandermonde determinant) to all orders of 1/N expansion in the case where the limiting eigenvalue distribution spans arbitrary (but fixed) number of disjoint intervals (curves).
