How to remove/replace NaN from multiple variables in workspace?
显示 更早的评论
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.

How are you generating A =, B = , C = ?
If these are in one matrix or cell array, then you could use fillmissing
or a combination of isnan logical index and replacement.
If you have a lot of unique variables, then you're out of luck and need to rework your code to avoid creating so many variable names.

"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
NaN
1
2
3
A =
0
0
0
1
2
3
