Plotting does not work well.

Code :

---------------------------------

T= 323.15;

A1= 4.01814;

B1= 1203.835;

C1= -53.226;

A2= 4.08245;

B2= 1346.382;

C2= -53.508;

Psat1= 10^(A1-(B1/(T+C1)));

Psat2= 10^(A2-(B2/(T+C2)));

x= [0:0.05:1]

y= ((Psat1)*(x))/((x)*(Psat1)+(1.-x)*(Psat2))

plot(x,y,'r+')

----------------------------------------

I want to plot the relationship between x and y. Although y is an expression for x, this code holds y at one value. I want to know what is the problem, and how to change the code to operate it as I intended.

T= 323.15; 
A1= 4.01814;
B1= 1203.835;
C1= -53.226; 
A2= 4.08245;
B2= 1346.382;
C2= -53.508; 
Psat1= 10^(A1-(B1/(T+C1)));
Psat2= 10^(A2-(B2/(T+C2)));

x= [0:0.05:1]
y= ((Psat1).*(x))./((x).*(Psat1)+(1.-x).*(Psat2))

plot(x,y,'r+')

use element-wise operation that is put .* and ./ instead of * and /
