How to reshape an array into 3 different matrix with different sizes?

I want to reshape A into 3 matrices m1,m2,m3:

    A=[1 2 3 4 5 6 7 8 9 4 5 3 5 3 2 5 4 2 4 7 5 ];

    m1=-9999*ones(3,3);
    m2=-9999*ones(2,2);
    m3=-9999*ones(2,4);

    the result should look like:
    m1=[1 2 3 ;4 5 6 ;7 8 9];
    m2=[4 5 ;3 5];
    m3=[3 2 5 4; 2 4 7 5];

"Reshape" normally means to change the shape but keep the same number of elements. Here, though, all the matrices have different numbers of elements. Please could you define the operation you need more exactly?

It looks like you just want to split the array up.

A=[1 2 3 4 5 6 7 8 9 4 5 3 5 3 2 5 4 2 4 7 5 ];

subData1 = A(1:9);
subData1 = reshape(subData1, [3 3]);

subData2 = A(10:13);
subData2 = reshape(dubData2, [2 2]);

subData3 = A(14:21);
subData3 = reshape(subData3, [ 4 4]);

This is all manually mind you. If your data structure will change dynamically you will want to try something different.

After the lines you've shown with m123=-9999*ones(...) do the following

      m1(:)=A(1:9);    
      m2(:)=A(10:13); 
      m3(:)=A(14:end);

and transpose as needed.
