ah, you wrote earlier that you have > three values, one for each X, Y and Z axis. for some reason I thought you have three values for each axis, meaning 9 values in total. but if you have only 3 values in total, it is not so obvious what they are. my best guess would be that they are direction, and then you can use them (after normalizing to unit vector) for one of vectors, for example Y. the other two vectors would have to be then picked at random, for example X.x = -Y.y; X.y = Y.x; X.z = Y.z; Z = X cross Y (or Y cross X, whichever works for away transform matrix)
