solve using matlab please

The natural frequency coefficient of a cylindrical shell clamped at one end and restrained by an attached stiff circular plate at the other end is given by: Ohm_nm = (1 - v^2) lambda^4_m/lambda^2_m + n^2 + 1.78n^2 lambda^2_m + 1/12 (h/R)^2 (lambda^4_m + n^4 + 1.78m^2 lambda^2_m) Where m and n are positive integers and lambda_m = (pi/4) (R/l) (4m + 1) Show that when n = 2, m = 1, h/R = 0.05, R/l = 0.1 and v = 0.3 Ohm_21 = 7.51587 times 10^-3
