i have a table with 3 variables a= 1,2,3,4,5,6,7,8 and fi= 0,10,20,30 and h which is depend on a and fi that contain 32 values. for example for fi=0 and a=1 >>h=1 fi=0 and a=2 >>h=1.02 ...... fi=30 and a=8 >>h=14800
is there any way in MATLAB to generate an equation for h in terms of a and fi??

There are a (literally) infinite number of equations that can be fit to any finite set of data. If you do not have a model of what kind of equation is appropriate, you cannot reject any of those equations as being less "correct" than the others. Unless you have a model of the actual equation, the probability of recovering the actual equation is zero. :(
