Hi All,
When i am calculating curve coefficients by enetring raw data
points for performance curve i am getting different values of curve
coefficient a,b,c,d,e,f each time where as my value of x,y, z is same why
is this so
if i have z= a+bx+cx2+dy+ey2+fxy then my a , b,c,d,e,f,y must represent
unique solution each time when my six values of z,x,y are same
Regards
Sambhav
