How do you use multiple indices to separate data and put in a structure?

I have a 3672 x10 matrix (A). I have a 1x300 array of indices (B). What I would like to do is get the data in matrix A between the indices in B and put each into a strucure. For example, I would like the first cell in the structure to contain these data:

A(B(1,1):B(1,2)-1,:)

I would like the second cell in the structure to contain these data:

A(B(1,2):B(1,3)-1,:)

I would like the third cell in the structure to contain these data:

A(B(1,3):B(1,4)-1,:)

...and so on thus that the last cell in the structure is

A(B(1,300):end,:)

So the structure will have 300 cells where each cell contains different snippets of data as defined above.

Here's one straightforward way

% Make up some data and indices
A = rand(3672,10);
B = 1:2:600;

% Preallocate the cell array
C = cell(300,1);

% Assign the cell contents
for ii = 1:299
    C{ii} = A(B(1,ii):B(ii+1)-1,:);
end

% Assign the last cell, which is a special case
C{300} = A(B(1,300):end,:);

I was pretty sure there was a simple vectorized way to do this, but it did not come to me right away. But then I remembered it:

% Make up some data and indices
A = rand(3672,10);
B = 1:2:600;

rowCountByCell = diff([B size(A,1)+1]);
C = mat2cell(A,rowCountByCell);
