If you want to replace the nan values by 0 for example
A(isnan(A))=0

Hi,
Another simple way to understand what's going on .
For me, it works well in R2014a. You only need to enter the matrix with NaN values without specifying the columns where NaN values are.
Here NaN values are replaced by 0s but you can easily modify it in the 8th line of this code:
%Input
m_data=C{1,1}; % Matrix with NaN values
%Code
s1=size(m_data,1);
for i= 1: s1
msubs=m_data(i,1:end); % Save existing data in ith row of m_data
msubs=msubs(isnan(m_data(i,1:end))==0); %Substitute matrix/ taking only non-NaN values
m_data(i,1:end)=0; %Erase all existing values in ith row of m_data and REPLACE by 0s
m_data(i,1:size(msubs,2))=msubs; %Substitute values without NaN
end
