I have a number of variables in workspace: A = [NaN; NaN; NaN; 1; 2; 3..]; B = [NaN; NaN; NaN; NaN; 4; 27; 31..]; C = [NaN; NaN; 10; 21; 34..]; et cetra and I need to replace NaNs from double with a 0.

"I have a number of variables in workspace: A... B... C ... et cetra and I need to replace NaNs from double with a 0."
Then you should redesign your code. Magically accessing variable names is one way that beginners force themselves into writing slow, complex, buggy code that is hard to debug. Read this to know more:

An example:
>> A = [NaN; NaN; NaN; 1; 2; 3]
A(isnan(A))=0
A =
NaN
NaN

A =
