Abstract
The saddle point equation described by the eigenvalues of N × N Hermitian matrices is analyzed for a finite N case and the scaling relation for the large N is considered. The critical point and the critical exponents of matrix model are obtained by the finite N scaling. The one-matrix model and the two-matrix model are studied in detail. Small N behavior for n-Ising model on a random surface is investigated.
