I'm new in matlab and I have a problem below

Cs=[0.15:0.15:0.45];
Cx=0.12;
C0= 0.08;
Erf=(Cs-Cx)/(Cs-C0)

Why Erf answer have only 1 answer, it should have 9 answers?

Why would it have 9 elements? If you use elementwise division instead of matrix division, it'll have 3.

Cs = 0.15:0.15:0.45;
Cx = 0.12;
C0 = 0.08;
Erf = (Cs-Cx)./(Cs-C0)
Erf = 1×3
    0.4286    0.8182    0.8919

If you transpose one of the vectors, you can get 9, but I don't know if that's intended.

Erf = (Cs-Cx)./(Cs.'-C0)
Erf = 3×3
    0.4286    2.5714    4.7143
    0.1364    0.8182    1.5000
    0.0811    0.4865    0.8919

Thank you for your advise, DGM.
