how to use a function with multiple inputs for a parameter?

Hi everyone, I'm trying to use this mathematica script (from Smith, J. M. (1950). Introduction to chemical engineering thermodynamics.) in Matlab. It isn't a complex script, but a I want to vary the temperature parameter (t) and obtain the fugacities coefficients for each temperature. How can I do this?

That's the function that I'm using in matlab:

function phi = phib(t, p, tc, pc, omega)

pr = p/pc; 
tr = t/tc; 
b0 = 0.083 - 0.422/tr.^1.6; 
b1 = 0.139 - 0.172/tr.^4.2; 

phi = exp( (b1*omega + b0)*pr/tr );

end

So, I use the file exeBolT.m to calculate the fugacity (phi)

clear all; close all; clc

t = [323.15; 400];
p = 0.25;
tc = 535.5;
pc = 41.5;
omega = 0.323;

phi = phib(t, p, tc, pc, omega)

Then, when I execute the file, I obtain

Error using  / 
Matrix dimensions must agree.

Error in phib (line 8)
phi = exp( (b1*omega + b0)*pr/tr );

Error in exeBolT (line 9)
phi = phib(t, p, tc, pc, omega)

Change all the / to be ./ for element by element division.
