Hi, i have a loop FOR i=1:N. For each 'i', i have to create 3 matrices that i want to store in the position 'i' of a new matrix(N,3). How can i do that? Thanks

Your Main matrix will be (N,3) size.
what is size of 3 matrices you are going to create?
& what do you mean by 'i' position?
Can you explain?

*First, i will create: * mat1(4,6) * mat2(4,6) * mat3(4,2) * and a value (an integer) * Then, i will execute those 3 matrices+the integer N time. * Finaly, i create the matrix of (N,4) just to memories those results that i have cited(the matrices+the integer)

Learn what a cell array is, how to use them, how to define them.
doc cell
You can also do similar things with structs.

So? A cell array can contain anything.
N = 10;
C = cell(N,3);
C{1,1} = pi;
C{1,2} = rand(3,3);
C1,3} = 'The sky is falling!';
etc.

ok now i have done that but when i do the implementation it doesn't post up the matrices with values ... but juste the dimmension of the matrices. And an other thing is that it post up juste the last raw of the matrix and not all the raws that he has memoriesed

you can try this:
N = 1;
MainMatrix = cell(N,4);
Result1 = zeros(4,6);
Result2 = zeros(4,6);
Result3 = zeros(4,2);
i = 2;
MainMatrix{1,1} = Result1;
MainMatrix{1,2} = Result2;
MainMatrix{1,3} = Result3;
MainMatrix{1,4} = i;
Also you can read
doc struct

If your matrices have the same size (nxm), you can use nxmxp matrix. For example
A1=[1 2;3 4;5 6];
A2=[7 8;9 10;1 1];
You can create the matrix B:
[n,m]=size(A1);
p=2;
B=zeros(n,m,p);
B(:,:,1)=A;
B(:,:,2)=B;
B

thanks for your answer, but no matrices don't have the same size. *mat1(4,6) *mat2(4,6) *mat3(4,2) *and i have a value also (integer)

i have to mention that the 3 matrices containt values( they are a result). In other word, i create the matrix of (N,3) just to memories the result i get each time because i need them later.
