How can I create a script that can perform division on both floating point numbers and fixed point numbers?

I want to create a script that can perform division on both double-precision floating point numbers and fixed point number. However, I noticed that fixed point numbers require a different function to perform division in the divide documentation.

How can I create a script that handles both types of numbers?

You can extract the numeric type of the numerator: 

function out = myDivide(u0, u1)
    T0 = 273.15;
    u0_k = u0 + T0;
    u1_k = u1 + T0;
    ntDiv = fixed.extractNumericType(u0);
    out = divide(ntDiv,u0_k,u1_k);
end

This uses the fixed.extractNumericType function, which works for double and fixed-point types. The output type will have the same scaling as the numerator.
