Covert matrix to sub-matrices

i have read a data file and received my 3003660x3 matrix, but these are various trials. is there any function that i can invoke to make this into 1476 separate 2035x3 matrices as that is the size of wach data set?

Answer 1

[Fangjun Jiang]

reshape()

Answer 2

[Bruno Luong]

A = reshape(yourdata, [2035,1476,3]);
A = permute(A,[1 3 2]);

Now invoking:

A(:,:,k) 

returns kth matrix of size (2035 x 3), for k=1, 2, .... 1476
