main question: how to make function vectorized

Write a function with header [ans]=mychoice(a,b,operation). The input argument, operation, is a string that is either ‘ Add’,’Subtract’,’Multi’, or ‘Square’ and ans should be computed as a+b, a-b, a.*b, and a.^b for the respective values for operation. Be sure to make your function vectorized. Hint: Use the strcmp function.
a = [1 2 4 5]
b = [1 1 2 1]
this is what I have so far and I do not know how to run the code for me to input a and b
function [answer] = mychoice(a,b,myoperation)
addition = 'Add';
difference = 'Subtract';
product = 'Multi';
square = 'Square';
if strcmp(myoperation,addition)
answer = a + b;
elseif strcmp(myoperation,difference)
answer = a - b;
elseif strcmp(myoperation,product)
answer = a .* b;
elseif strcmp(myoperation,square)
answer = a .^ b;
else
fprintf('Invalid Operation, check your input\n');
end

Vectorization means that the function should be able to accept arrays and apply an operation on all of its elements. In that sense, your function is already vectorized. You need to call the function like this in the command window
a = [1 2 4 5];
b = [1 1 2 1];
mychoice(a,b,'Subtract')
