 ** @param Y data matrix Y.
 ** @param numDataX number of vectors in @a X (columns of @a X)
 ** @param numDataY number of vectros in @a Y (columns of @a Y)
 ** @param comparison vector comparison function.
 **
 ** The function evaluates @a function on all pairs of columns
 ** from matrices @a X and @a Y, filling a @a numDataX by @a numDataY
 ** matrix.
 **
 ** If @a Y is a null pointer the function compares all columns from
 ** @a X with themselves.
