I have N number of measured data
[G(x1), G(x2), G(x3),.....G(xN)]

which are, in effect, values of

G(x) = Integral ( F( sqrt(x^2 + y^2)) * S(y)) .

Here, S is a known array [S(y1), S(y2), S(y3),.....,S(yK)] corresponding to the array of y (i.e., [y1, y2, y3,.....,yK]).

Similarly, x is an array [x1, x2, x3,........xN].

How do I find out F(x) ? I am a user of MATLAB in Windows platform, also can program in FORTRAN.
