Deleting empty variables from cell variables with respect to rows.

Suppose, I have this code excerpt:

clc, clear, close all;

A{1}=[1,4,1,6,130,30,4;1,6,3,6,130,30,4;1,6,2,1,130,30,4;1,1,2,2,130,200,4;1,4,1,1,130,30,4;
    1,2,2,2,130,100,4;2,4,1,4,75,30,4;2,6,1,4,75,30,4;2,4,5,2,75,30,4;2,2,3,2,75,100,4;
    2,5,4,6,75,20,4;2,6,5,5,75,30,4;4,1,5,6,117,200,3;4,2,3,5,117,100,3;4,3,2,4,117,9,3;
    4,2,3,1,117,100,3;4,5,3,1,117,20,3;4,1,2,6,117,200,3;4,2,2,3,117,100,3]

A{2}=[1,1,1,6,130,200,4;1,3,3,4,130,9,4;1,2,3,3,130,100,4;1,4,3,5,130,30,4;1,3,1,2,130,9,4;
    1,1,3,4,130,200,4;2,6,3,5,75,30,4;2,6,3,6,75,30,4;2,1,3,2,75,200,4;2,6,1,5,75,30,4;
    2,5,1,2,75,20,4;2,5,2,1,75,20,4;4,6,2,6,117,30,3;4,2,2,3,117,100,3;4,3,3,3,117,9,3;
    4,6,5,2,117,30,3;4,6,2,3,117,30,3;4,6,3,3,117,30,3;4,3,5,2,117,9,3]

for i=1:length(A)
    for j=1:19
        filtered{i,j}=A{i}(ismember(A{i}(:,1),[j]),:); 
    end
end

The filtered content consists of 2x19 cells. I would like to remove the empty variables (The ones with []) from filtered. I tried this code,

A=filtered(~cellfun(@isempty,filtered))

But it merges the 2 rows into 1 column. I would like to maintain the existing row position. In other words, it should remove the empty cell variables based on its row.

How can I get about this?

Did a bit of tweaking. This may not be the best solution.

for i=1:length(A)
    for j=1:19
        filtered{j}=A{i}(ismember(A{i}(:,1),[j]),:);
    end
    newfiltered{i}=filtered(~cellfun(@isempty,filtered(:)));
end

You can still do this

A=filtered(~cellfun('isempty',filtered)),

but reshape it afterward

 A=reshape(A,2,[]);

assuming it will always be reshapeable into something 2xN.
