how to get the first position in the array and get size array contains matrices

Dear all,

I have a problem and I hope somebody can help.

I want to get the first index in the array, the array contains matrices and I want to get the first matrix, then I will do a loop start from the second matrix to the last matrix.

and I want to get size, I use "size" function but it returns " 4 2", how can I use the first number

note: assume array come form parameter of the function and it's hidden I don't know what array contain and the size of the array is unknown

example of the array :

m1=[ 0 1; 0 0];
m2=[ 0 1; 0 1];
m3=[ 1 1; 0 0];
m4=[ 1 1; 0 1];
array=[m1 m2 m3 m4];

index1=array(1);%not working

I hope I am clear enough.

Thanks in advance,

Ghaida

Use a cell array:

>> C = {m1,m2,m3,m4};
>> C{1}
ans =
   0   1
   0   0
