Matlab Programming.Help!!!

[Nikolas83]

Hello once again…
I am doing an exercise in matlab programming and I wondered if somebody of you could me help..
I want the matrices that I have in my problem to put them in a line(array)..
for example I have matrices A=[2 4; 5 6 ] and B=[4 6 7;6 3 4 ]
and i want to put the elements of matrices in one array..
to do this think r=[2 4 5 6 4 6 7 6 3 4]..
I do some thinks but..i did not find anything good..

Try this:
A = [2 4; 5 6];
B = [4 6 7; 6 3 4];
r = [reshape(A',1,[]) reshape(B',1,[])];

Try this:
A = [2 4; 5 6];
B = [4 6 7; 6 3 4];
r = [reshape(A',1,[]) reshape(B',1,[])];

echo47 Thanks a lot..my friend...
i think its match in my exercise.

Hello..Again
I think that my problem isnt solve yet..
Because the matrices have the form below...

A = zeros(2,2,3);
B = zeros(2,1,3);
A,:,1) =eye(2);
A,:,2) = [-1.5 0.1;-0.2 1.5];
A,:,3) = [0.7 -0.3;0.1 0.7];
B,:,2) = [1;-1];
B,:,3) = [0.5;1.2];

and if i try to run with the 'reshape' commant..
It saw to mee the below error..

Error using ==> ctranspose
Transpose on ND array is not defined.

if anyone has an idea..pleasantly i accept it..

Thank you.
----------
Just found it..
the form command in mine case is
r = [reshape(A,:,1)',1,[]) reshape(A,:,2)',1,[]) reshape(A,:,3)',1,[]) reshape(B,:,2)',1,[]) reshape(B,:,3)',1,[])]

I write because maybe that is useful for another friend with the same request..

do that after u Defined matrix A & B


c =[A( : ) B ( : ) ]
c = c'

Hi,
You can solve your problem by create a function to reshape your matrix to the form you need and then you concatenate them in the way you wnat, her is the Code of the function...

function x = change_matrix(a)
B = a;
Bx = [];
siz = size(B);
for i = 1 : siz(1)
    Bx = [Bx B(i,:)];
end
x = Bx;

And then you can call this function from the Command Window or from your M-file to perform your operation as follow, you fist have to define your matrices

>> A = [2 4; 5 6 ];
>> B = [4 6 7;6 3 4 ];
>> C = [change_matrix(A) change_matrix(B)];

then matrix C will equal..
C = [2 4 5 6 4 6 7 6 3 4];
