I have a cell matrix like this

I need to generate matrix for the non empty cell in these format and arrange row by row ( form above to below)

A = [ 16 3

21 3

16 4

22 4

4 5

9 5

16 5

22 5

. . ] so on.

How can we do that?

在 MATLAB Online 中打开

c = cell_array.';
ix = cellfun('isempty',c);
w = cellfun(@flip,c(~ix),'un',0);
Wanted = cat(1, w{:})

Thanks for the reply.

I upload the code I am working on, the function I want to need to generate matrix for the non empty cell in these format and arrange row by row ( form above to below) called " Location ". you can find it in the for loop.

And AA is the wanted matrix like I showed in the first comment.

clc

clear all

baseFileName = 'I-3.png'; % donot foregt to chage the video name

% baseFileName = 'i-4.png';

fullFileName = imread (baseFileName);

Z = rgb2gray(fullFileName);

imshow (Z)

[counts,x] = imhist(Z);

% %stem(x,counts)

T = otsuthresh(counts);

BW = imbinarize(Z,T);

imshow (BW)

BW = edge(BW);

imshow (BW)

[row,col]=find(BW==1);

imshow(BW)

hold on

plot(col,row,'xc')

hold off

Intensity_at_location = BW(5,3);

[v,q] = size (BW);

for i = 1 : v-1

for j = 2 : q-1

% if BW (i,j)==1

Int = BW (i,j);

Intleft = BW (i,j-1);

Intright = BW (i, j+1);

if isequal (Int,Intleft,Intright)

location{i,j} = [];

elseif Int == 0 && Intleft == 0 && Intright == 1

location{i,j} = [];

elseif Int == 0 && Intright == 0 && Intleft == 1

location{i,j} = [];

else

location{i,j} = [i j];

end

% else

end

% end

% %

% A = cell2mat(location);

% imshow(A);

% c = cell_array.';

ix = cellfun('isempty',location);

w = cellfun(@flip,location(~ix),'un',0);

AA = cat(1, w{:})

Thanks in advance

Then don’t transpose ;).
