Find coordinates of point on original image after using interp2

Hello,
So I have a matrix A (10x10) of integers. I use interp2 in order to interpolate A into B, which is another matrix of 9x8.
The code I'm using is:
A=round(rand(10).*10);
[x_a,y_a] = meshgrid (linspace(1,10,8),linspace(1,10,9));
B = interp2 (A,x_a,y_a,'linear');
Is there any method to locate the coordinates of a point of matrix A within matrix B?
I am asking this because I have an image (A) which then I apply some geometric transformations (with some additions, substraction, multiplication, not with imwarp or any MATLAB builtin function) to obtain B. On the original image A I know the coordinates of a specific point, therefore I would like to know the best approximation of that point on image B.
Any help would be appreciated. Thank you
