Please help to write code with bit details, as I am new in matlab.

Hi everyone, I am quite new in matlab. I have 3 variables is listed below

Wd=0.04:0.04:2, mh=.1:.1:5 and Dh=.001:.001:.03
Here  N2=Wd/0.04; N1=50/N2; Ld=(N1*N2*a^2)/Wd;

I have to calculate several thing based on these variables, such as

A=Wd*Dd,    
vh=mh/A;
Reh=(dh(i)*vh*Dh)/uh(i), Here i=1:1:50,
Q(i)=(Th(i)-Tc(i))/Rt(i)
 q(i,j)=Q(i)/At;
  Th(i+1)=(mh*cph(i)*Th(i)*1000-q(i))/(1000*mh*cph(i)); 
  Tc(i+1)=(mh*cph(i)*Tc(i)*1000-q(i))/(1000*mh*cph(i));  
  P=N2*(Q(i))*Neff;

there is some more related calculation. P will be function of variable P(Wd, Dd, mh), may be it will give 75,000 data points in X,Y,Z Plane.

I know its a big question for you all. may be need more time to read it. If someone help me to write this code, would be really really very help.

MATLAB has got very easy and vast documentation, what have you attempted so far?
