Hello all,
I need to replace the NaN values with a blank space in either a matrix or cell array. What should I do?? On trying the below code with cell array, I got the following error:
a(cellfun(@isnan,a)) = {[]}; Error: Function name must be a string.
I am using Matlab 7.0.1 (R14).
How should I give the isnan function???
Thanks in advance for the help.

R14 is very old now. I'm not sure if cellfun accepted function handles freely in this version. But you can emulate this simply by a loop:
for k = 1:numel(C)
if isnan(C{k})
C{k} = '';
end
end
Replacing NaN values by '' in a matrix will not work: All elements of a matrix need to be the same type. While NaN is a double or single, the empty string is a char.

@Vasishta Bhargava: numeric arrays cannot contain characters, so what you want is not possible. The value 65 is the character encoding number for the letter 'A'. You were told this in response to your earlier comment:

Please stop hijacking other people's threads. You have been given the same information twice now, it will not change if you ask again.

A={nan 1 2 nan 3 'r'}
A(cellfun(@isnan,A))={''}
