How can I change from Cell to Double and writing in many lines

Dear, I would like solve a problem about transformation and save in the file

I have a file A that is 19x1 cell. And in each cell I have a matrix 6x6. for example A(1,1) = 6x6 Double, A(2,1) = 6x6 Double ...A(19,1) = 6x6 Double.

I would like write the file A in Double and each matrix stay in one line with 36 column and write (save) these data in the archive.

For example:

From A(1,1) = 6x6 Double to A(1,36)

From A(2,1) = 6x6 Double to A(2,36)

From A(3,1) = 6x6 Double to A(3,36)

.

.

From A(19,1) = 6x6 Double to A(19,36)

The code below should do what you want.

%generate input
A=cellfun(@(x) {x+rand(6,6)},num2cell(1:19)');

%convert the cell contents to row vectors
B=cellfun(@(x) reshape(x,1,[]),A,'UniformOutput',false);

%concatenate into a single double array
C=cell2mat(B);

Thank you for answer. It almost works.

But, instead of program write the first line in the column 1 until 6, second line in the column 7 until 12, third line in column 13 until 18 ...and etc,

the program wrote the fisrt column of Matrix 6x6 in Column 1 until 6, the second column of Matrix in column 7 until 12...and etc.

Do you know how can I change it ?

I took out ' in the first algoritm but it don't works

That first line is just generate some example data to work with, so that shouldn't be edited.

Matlab is column-dominant, so the reshape in the second statement reads column by column. If you want to change that to row by row you can transpose the matrix:

B=cellfun(@(x) reshape(x.',1,[]),A,'UniformOutput',false);

Thank you very much. It works.

I changed many things but it I didn't not.

Now it is working \o/

Let me do more one question, please.

Is possible I write these lines starting in column 7 ?

For example:

The program is writing:

Line 1 and Column 1 until 36

Line 2 and Column 1 until 36

.

.

Line 19 and colund 1 until 36.

I would like write starting in column 7 until 42.

line 1 and Column 7 until 42

line 2 and Column 7 until 42

.

.

line 19 and Column 7 until 42.

Is it possible ?

thank you

Rewrite the anonymous function inside the cellfun to suit your needs.
