Reading variable names from a loop

I have a long list of variable names that I want to create in my loop. For example,

A={'BHCK0081'
'BHCK0276'
'BHCK0277' etc...};

on the other hand I have vector B which is a double vector that has the same size of A. if I want to select these variable in a loop and assign a certain computation to get them. For example,

for i=1:length(A)
I want to get BHCK0081 as variable 1=B(j)^2  
BHCK0276 as variable 2=B(j)^2 
 and BHCK0277 as variable 3=B(j)^2  etc...
end

How can I assign these variable names using vector A ?
