How to get the first Ten Solutions of nonlinear equations

how to get the only one root of f==0 and the first 10 positive roots of g==0,

and when i change the value of

omega

it will also get the roots,

codes are as this

clc;
clear all;
close all;


g=9.8;

h=20;

hgang=20;

omega=4;

nu=omega^2*hgang/g;

f=(m0)*tanh(m0)-nu;

g=(i*m1)*tanh(i*m1)-nu;

thanks a lot!!!
