Taking in 2 array variables, my output variable is a single number rather than an array. Any suggestions to get my output in an array?

alpha = 30;
theta_1 = 0:360;
omega_1 = 360;

theta_2 = atan(tan(theta_1)/cos(alpha))
omega_2 = sec(theta_1).*sec(theta_1).*omega_1/((sec(theta_2)).*(sec(theta_2)).*cos(alpha))

If I remove the division, omega_2 is an array, but with it omega_2 is a single value and I don't understand why.

Any help would be greatly appreciated!

I guess you probably want to use the:

A ./ B

operation instead of the straight divide "/".

Also as a recommendation, break up your expression into smaller pieces for easier debugging. e.g.:

numerator = sec(theta_1).*sec(theta_1).*omega_1;
denominator = (sec(theta_2)).*(sec(theta_2)).*cos(alpha);
answer = numerator ./ denominator;

or even finer pieces.

Blessings,

"...operation instead of the straight divide "/"."

Which in MATLAB are called ridivide and mrdivide respectively. Read more about the difference:
