MATLAB: How to find all the value

variable

u = 10:100:250; %[m/s]

D = 0.002; %[m]




v = 2*10^-7; %[m/s]
P = 1;
k = 0.1; %[w/mk]

ks = 60.6; %[w/mk]
t1 = 0.0002; %[m]
t2 = t1; %[m]
H = 0.002; %[m]
qw = 2:10:20; %[Mw/m^2]
w = 0.002; %[m]
R = (u*D)/v
Nu = 0.023*(R.^0.8)*P.^0.4
hc =(Nu*k)/D
bw = hc/(ks*t1)
b1 = sqrt(bw)
b2 = b1;
A1 = ((coth(b1*w/2)/b1*ks))+((t1/t2)*coth(b1*H))/(b1*ks)

Nu =

A1 =

I'm not able to get the all values of A1. Can you please point out to me how to find the all the value of A1?

Best Answer

Use dot slash rather than slash to do an element-by-element divide:
A1 = ((coth(b1*w/2) ./ b1*ks))+((t1/t2)*coth(b1*H)) ./ (b1*ks)
