How to store function output as a matrix?

Hi! I need help storing the output of P as a matrix so it would look like:

T P

0 corresponding value from P eqn

10 corresponding value from P eqn

20 corresponding value from P eqn

etc.

I am not the best with matlab, but any help would be appreciated. When I run the code, it becomes split apart. Thanks!

out = [];
for T = [0:10:100]
    
    Volume = [0.0735560; 0.0736893; 0.0738233; 0.0739572; 0.0740910; 0.0742250; 0.0743592; 0.0744936; 0.0746282; 0.0747631; 0.0748981];
    V0 = Volume(1,1); % index
    V100 = Volume(11,1); % index
    
    Temp = [0;10;20;30;40;50;60;70;80;90;100];
    T0 = Temp(1,1); % index
    T100 = Temp(11,1); % index
    
    P = V0 + (((T - T0)*(V100 - V0))/(T100 - T0)); % simple equation

    out = [T P]
end

out = zeros([],2);
count = 0 ; 
for T = [0:10:100]
    
    Volume = [0.0735560; 0.0736893; 0.0738233; 0.0739572; 0.0740910; 0.0742250; 0.0743592; 0.0744936; 0.0746282; 0.0747631; 0.0748981];
    V0 = Volume(1,1); % index
    V100 = Volume(11,1); % index
    
    Temp = [0;10;20;30;40;50;60;70;80;90;100];
    T0 = Temp(1,1); % index
    T100 = Temp(11,1); % index
    
    P = V0 + (((T - T0)*(V100 - V0))/(T100 - T0)); % simple equation
    count = count+1 ; 
    out(count,:) = [T P]
end 

OR

T = [0:10:100] ; 
N = length(T) ; 
out = zeros(1,N);

for i = 1:N 
    
    Volume = [0.0735560; 0.0736893; 0.0738233; 0.0739572; 0.0740910; 0.0742250; 0.0743592; 0.0744936; 0.0746282; 0.0747631; 0.0748981];
    V0 = Volume(1,1); % index
    V100 = Volume(11,1); % index
    
    Temp = [0;10;20;30;40;50;60;70;80;90;100];
    T0 = Temp(1,1); % index
    T100 = Temp(11,1); % index
    
    P = V0 + (((T(i) - T0)*(V100 - V0))/(T100 - T0)); % simple equation
    count = count+1 ; 
    out(i) =  P ;
end 
[T' out']

Thank you! The latter code works perfectly. I've spent so long trying to figure it out.

out = [];
for T = [0:10:100]
    
    Volume = [0.0735560; 0.0736893; 0.0738233; 0.0739572; 0.0740910; 0.0742250; 0.0743592; 0.0744936; 0.0746282; 0.0747631; 0.0748981];
    V0 = Volume(1,1); % index
    V100 = Volume(11,1); % index
    
    Temp = [0;10;20;30;40;50;60;70;80;90;100];
    T0 = Temp(1,1); % index
    T100 = Temp(11,1); % index
    
    P = V0 + (((T - T0)*(V100 - V0))/(T100 - T0)); % simple equation
    out = [out;T,P];
end

This is not advised.
