how to program this function

I am trying to program a function (as a separate matlab function, not in the main script) which takes values for variables from different arrays and uses them in the calculation. Here is the function

I am running into a problem because I need to test every A and B value for each coordinate ([1,8], [3,9], [4,2], [9,4]), but since the arrays are different sizes it keeps returning errors.

None of the methods I have tried has worked. The different example arrays I have are as follows.

a = [2:0.2:20];
b = [2:0.2:20];
x = [1,3,4,9];
y = [8,9,2,4];
%numerical values will change based on parameters the user enters. Will
%always be the same size though.

Reorient the vectors. If you're using R2016b or newer, you can do this:

c = sum(sqrt((a-x').^2 + (b-y').^2),1)

otherwise, you can use bsxfun(). The point is to generate a distance vector for each x,y pair, resulting in a 2D array. Then just sum the rows.
