Mathematica FindRoot to Matlab

May I ask how to put the following Mathematica code into Matlab?

mvel1[n_, H_, f_] := v /. FindRoot[freq[v, n, H, 2.2, 1800, 1500] ⩵ f, {v, 1500.1, 1799.9}]

I need to create a function like

funciton mvel1=mvel1_fun(n,H,f)
...
end

The Matlab freq function is

function freq=freq_fun(v,n,H,m,cb,cw)
    dum1=sqrt(cw^(-2)-v^(-2));
    dum2=sqrt((cw^(-2)-v^(-2))/(v^(-2)-cb^(-2)));
    freq=1/(2*pi*H*dum1)*(pi*n-atan(m*dum2));
end

Thank you!

mvel1 = @(n, H, f) fzero(@(v) freq_fun(v, n, H, 2.2, 1800, 1500) - f, [1500.1, 1799.9]) ;
