Given a center, sum adjacent pixels

Hi, suppose I have a matrix A and I have a center (for example (10.3,14.6)). Now I want to calculate the value of the center in this way
value = w1*A(10,14) + w2*A(10,15) + w3*A(11,14) + w4*A(11,15)
w1, w2, w3, w4 are the values of the weigths that are proportional to the distance of the pixel from the center.
What is the most correct way to evaluate w1, w2, w3, w4? I want that the weigth of the pixel that is closer to the center higher and the weigth of the pixel that is farther to the center lower and so on.
My hyphotesis is something like this:
w1=0.7 * 0.4 ; w2=0.7*0.6; w3=0.3*0.4; w4= 0.3*0.6
