Unit Converter: Miles to Feet. Having trouble outputting an array.

I am trying to write a script that converts miles to feet. The output can be a single number or an array of numbers.

When I run the function it works well with one numer but when i input multiple numbers it says there are too many input arguments.

Here is my code:

function [feetConversion] = mileConverter(miles)

    unitConvCalc =  miles * 5280;
    feetConversion = [unitConvCalc]
    
end

How are you inputing more than one number?

I figured it out.

I was doing mileConverter(1,2,3) when I should've done mileConverter([1,2,3])
