Help writing two equations in Matlab (Please view Attachment)

I have two equations and I want to loop a value for 'n' from 1 to 50. I want to put these equations in so that Ln (equation 1) is part of Bn (equation 2). The constants are given below:
S = 1200;
Lx = 0.127;
Ly = 0.203;
k = 0.16;
I have tried this and all it gives for Bn is negative values of zero which is not right:
Ln = zeros(1,nmax); Bn = zeros(1,nmax);
for n = 1:nmax
Ln(n)= ((2*n-1)*pi)/(2*Lx);
Bn(n) = ((2*S)/(k*Lx))*(((-1)^n)./((Ln(n).^3).*cosh(Ln(n)*Ly)));
end

I get ‘B(n)’ as a rapidly decaying oscillation asymptotic to 0 when I write my own code for your equation. If this is not the result you expect, and you copied your function correctly, check your constants.

It is because according to your formula the values for Bn become extremely small. And because the first value is -10.07 which his much much larger, the later entries in the array will appear as 0. For example Bn(50) is 1.4e-112
Also if you use a for loop, there is no need to put a dot in front of the / or the *
