Funny bug with respect to NaN value,

declare X as

X = [1 2 3 4 NaN];

and then use,

max(X) yields, 4

min(X) yields, 1

but in workspace the Min and Max column displays NaN and NaN,

[PS : I agree that NaN values are always ignored.]

Is this a required feature or a bug ?

What exactly is "in workspace"? Do you mean the workspace browser? If so, which Matlab version are you using?

[Anil]

Its the workspace window or browser of Matlab, I noticed it in both R2007b and R2012a

This is an intended feature in the workspace browser in MATLAB 7.9 (R2009b). The Min and Max values in the workspace browser do not ignore NaN by default. You can make the workspace browser ignore NaN by changing the settings under Preferences->Workspace.

Aah..! Yes you are right... thanks... :)
