Hi I have written this code to calculate T1...T5 value. Where every loop works with value of R1...R5. But it does not work. Anyone please tell me what type of mistake i made to write this code.

clear all
%%%Thermal resistance
R1=0.0016;
R2=0.0018;
R3=0.00036;
R4=0.00032;
R5=0.0005;
p=25000;
Tc=25;
Tj=125;
%%%%Temperature of each layer
x=6;y=6;
while x<6&&y<6
  x=x+1;
  y=y+1;
Ty=Tc+(Rx*p);
end

Rx is an undefined variable, you need to put R1,R2,...,R5 in a vector

%%%Thermal resistance
R1=0.0016;
R2=0.0018;
R3=0.00036;
R4=0.00032;
R5=0.0005;
R=[R1 R2 R3 R4 R5];
p=25000;
Tc=25;
Tj=125;
%%%%Temperature of each layer
x=0;y=0;
while x<5&&y<5
  x=x+1;
  y=y+1;
Ty(x)=Tc+(R(x)*p);
end
Ty
