M=[];
M=dlmread('data.txt', '\t');
dataArray=M;
C= corrcoef(M(:,1:end));
imagesc(C);
cb = colorbar;
ylabel(cb, 'Correlation Coefficient');
moo=sqrt(C^.2)
moos=[]
for l=0:.1:1;
moo(moo<l)=0;
moos{end+1} = moo;
moos(moos>0)=1;
The last opertaion fails since > is an undefined operator for input arguments like cell. I unsuccessfully tried to make a function for the last line and implement it in cellfun. What would be the proper syntax here?

"The last operation fails since > is an undefined operator for input arguments like the cell."
You cannot directly perform the comparison on cell array. you need to access its element using curly brackets and then operate on them. For example, the following syntax will work
moos{end}(moos{end}>0) = 1;
to apply this operation to all elements of moos use cellfun as following
moos = cellfun(@(x) x.*(x<0)+(x>0)*1, moos, 'UniformOutput', 0)

I see, I saw the second format on another forum page, can you explain the @(x) x.*(x<0)+(x>0)*1 piece. For all entries if x<0 or x>0 set equal to 0?

x.*(x<0)+(x>0)*1 means that if entries are less than 0 than don't change them but if they are greater then 0, then make them 1. This is what I thought you are trying to do from your line
moos(moos>0)=1;

before starting the iteration,
mos=[];
"before starting the removal of the next mo", most probably inside-end of the iteration,
mos{l*10}=mo;

This adds the entry only to the last space of mos{} All other entries are empty,
Update: Got it working with the following code.
moos=[]
...
for l=0:.1:1;
moo(moo<l)=0;
moos{end+1} = moo;
end;
...
