How to create a function that accepts a vector input

I have created the function below to calculate the temperature distribution inside of a fuel cell:

function TD = temp_distribution(r)

q = (7200*(1-((2.4048*(0.7620/244)^2)/4)+((2.4048*(0.7620/244)^4)/64)-((2.4048*(0.7620/244)^6)/2304))*(cosd((pi*150)/610)))


TD = (1500-((q*r^2)/(4*0.05)));

end

And I would like to input a radius vector in order to find the heat distribution throughout the fuel cell; so, in a seperate file I created a radius vector and attempted to input it into my function.

rad = [0.001:0.001:0.762];

temp = temp_distribution(rad);

However, when I try to run this code I get an error with the fuction file. When I try to run the fuction with a single number input, it works just fine. So my question is, how can I change my fuction so that it will take the vector input, apply the function to every value in the vector, and then output a new vector?

You will need to change all of the linear algebra operators (i.e. "matrix" operations) to element-wise operations (i.e. "array" operations):

E.g.

/ change to ./

* change to .*

etc.

Using MATLAB requires knowing the difference between array and matrix operations.
