show images contained in a cell array in a single window with montage?

Hi everybody! I've a cell array containing the images I want to present in a single graphic window through montage function , here the code so far but doesn't work correctly :

   %a from previous instruction is : 1 x 14 cell containing the images (uint8)
%contatore is the number of images i've generated 
for i = 1 : contatore

    montage(a{i},'Size',[2 7])

end

How can I make it work? Thanks Another point : there is a way to make the size of montage adjust itself instead, depending on the images it has instead of writing :'Size',[2 7] ? Thanks again

Can you share your array image?

[federica pasquali]

a =

    1×14 cell array

    Columns 1 through 5

      {246×272×3 uint8}    {246×272×3 uint8}    {246×272×3 uint8}    {246×272×3 uint8}    {246×272×3 uint8}

    Columns 6 through 10

      {246×272×3 uint8}    {251×280×3 uint8}    {240×264×3 uint8}    {232×248×3 uint8}    {232×264×3 uint8}

    Columns 11 through 14

      {232×264×3 uint8}    {168×200×3 uint8}    {238×272×3 uint8}    {232×256×3 uint8}

this is my cell array and i want to do a montage of all the image contained in the array a i've tried with this for loop but doesn't work :

for i = 1 : 15
  figure('Name','1A')
   montage(a{i:15) ,'Size',[2 7])
end

because everytime it opens a new figure for every image and i want only a figure with all the images

Here im_array is the cell array

    montage(im_array)

[federica pasquali]

if i do this : montage(a) it doesn't work and i don't know why

Make sure a is a cell or string array of character vectors

[federica pasquali]

how can i change a cell array which contains images in the format unint8 in a cell or string array of character vectors and show them with montage?
