Having problem inserting and accessing the values from that cell array

Am trying to insert a 3 matrix of m x n size into a cell array by using a loop statement like

for i=1:3

a{i} = {M }; (M is the matrix which comes after calculation inside loop and am storing the calculation inside M and then transferring to cell )

end

Now i want to access the values such that

a{1,1} will have the mxn double matrix in it

but currently within the a cell it is creating one more cell of 1x1 and then inside that it is creating the mxn matrix

I want to directly insert the values in a{1,1},a{1,2},a{1,3} instead of a{1,1}{1,1} , a{1,1}{1,2} , a{1,1}{1,3}

a = cell(3,3) ;
M = rand(3) ;
for i = 1:3
    for j = 1:3
        a{i,j} = M ;
    end
end
