how to run a recursive solution

load 'gastemperature.m' 
Tgbv=gastemperature(i) 
load 'gastemperaturetestcell.m' 
Tgtc=gastemperaturetestcell(i) 
Tgbv1=gastemperature(i+1) 
Tgtc1=gastemperaturetestcell(i+1) 
load 'watertemperature.m' 
Tw=watertemperature(i) 
h=input('enter h value') 
P=1.5922 
[Ta,P]=hworkf( Ta,P,h,Tgbv,Tgtc,Tw,Tgbv1,Tgtc1 ) 
while P<1.66 &Ta<330.15 
return 
end

Please help with the following issues:

1. how do i write the code such that it runs recursively until the condition 'P<1.66 &Ta<330.15' is met?
2. Tgbv,Tgtc,Tw,Tgbv1& Tgtc1 are each from an array of data. How do I write the code such that a new value is picked from these arrays upon every solution
3. how do I write the code such that the Ta and P from each solution is taken into the next solution
4. how do i save the outputs(Ta and P) from each iteration as arrays? thanks.

1.- % make sure you have defined a value for ( Ta,P,h,Tgbv,Tgtc,Tw,Tgbv1,Tgtc1 ). In your code above Ta is missing

load 'gastemperature.m' 
Tgbv=gastemperature(i) 
load 'gastemperaturetestcell.m' 
Tgtc=gastemperaturetestcell(i) 
Tgbv1=gastemperature(i+1) 
Tgtc1=gastemperaturetestcell(i+1) 
load 'watertemperature.m' 
Tw=watertemperature(i) 
h=input('enter h value') 
P=1.5922 
[Ta,P]=hworkf( Ta,P,h,Tgbv,Tgtc,Tw,Tgbv1,Tgtc1 )
solutions(1,:) = [Ta,P];
i = 2;
while (P<1.66 & Ta<330.15)
Tgbv=gastemperature(i);
Tgtc=gastemperaturetestcell(i);
Tgbv1=gastemperature(i+1); 
Tgtc1=gastemperaturetestcell(i+1); 
Tw=watertemperature(i); 
[Ta,P]=hworkf( Ta,P,h,Tgbv,Tgtc,Tw,Tgbv1,Tgtc1 );
solutions(i,:) = [Ta,P];
i = i +1;
end
