Hey
I have a cell array A
A= {NaN,-1,-1,0.8,-0.6,[],[]; NaN,NaN,0.9,1,NaN,-0.05,0.4; -1,NaN,NaN,0.7,0.2,NaN,0.79}
I want to remove negative and NaN values from all the rows and store result in a cell array like:
A{1,1}={0.8}
A{2,1}={0.9,1,0.4}
A{3,1}={0.7,0.2,0.79}
Thanks in advance.

NoNan = @(V) V(~isnan(V));
NewA = arrayfun(@(ROWIDX) NoNan([A{ROWIDX,:}]), (1:size(A,1)).', 'Uniform', 0);

I did not explicitly take empty into account, but the [A{ROWIDX,:}] will effectively discard empty matrices.

Yes very efficient method. Thank You so much

A= {NaN,-1,-1,0.8,-0.6,[],[]; NaN,NaN,0.9,1,NaN,-0.05,0.4; -1,NaN,NaN,0.7,0.2,NaN,0.79} ;
% Replace empty cells with NaN's
idx = cellfun('isempty',A) ;
A(idx) = {NaN} ;
% convert to matrix
B = cell2mat(A) ;
iwant = cell(size(B,1),1) ;
for i = 1:size(B,1)
T = B(i,:) ;
T = T(~isnan(T)) ;
iwant{i} = T(T>0) ;
end
