Using the result as a input in the loop again

I am writing a program for a model which capture the moiture from the air. I am new to the Matlab

I attached the program below

clear

clc

aw=0.7;

Ps=(2.339);

RH=95;

Tgas=293;

Tsol=293;

H=18.015;

A=0.25;

%membrane resistance (P/t)

P=(0.00000000001206);

t=(0.000055);

K=(P/t); %Resistivity constant

Cl=123.9;

mW=100;

for x=1:60*60;

t(x)=x;

Ms=(Cl/164.0);

Mw1(x)=(mW+M(x)/18.0); ---input the previous result (x-1 ) here again in the loop to find the result for the current loop

Y=Mw1(x)+(3*Ms);

Xw(x)=(Mw1(x)/Y);

Pvl=Xw(x)*Ps*aw;

Pva=(RH.*Ps)/100;

X=(Pva-Pvl(x));

Gv(x)=(K)*(X(x));

M(x)=Gv(x)*H*t(x)*A; ---- Result of the current loop for the next interation

end

How can I use the result from the previous loop to do the calculation in current loop. I need help.Thanks!

Change

Mw1(x)=(mW+M(x)/18.0);

to

% first iteration assumes Mw1(0) = 0
if x==1
    Mw1(x)=mW;
% later loops access the value from the earlier iteration
else
    Mw1(x)=(mW+M(x-1)/18.0);
end

Thanks a lot!!
