I had tried to use this way,but there is a defualt. I cann't break in points,so this only got some approximate values,you know that 2D lookup table can break in some others values using algorithms ,the real matrix T is more vectors than only T.
when I use the function find(),it only find the values which excist in only T
thanks very much!
