for example i have all data for x , y and z
x=[2.6,5.2,14,23.3,28.3,2.6,5.2,14,23.3,28.3,2.6,5.2,14,23.3,28.3]
y=[3.5,6.9,17.7,29.1,35.2,3.5,6.8,17.5,28.7,34.8,3.4,6.6,16.9,27.6,33.5]
z=[450,450,450,450,450,350,350,350,350,350,250,250,250,250,250]
and as you can see from the attachment
if i want to know what is
y =
when x= 20
and z= 367
is ther any function to do that ??????
