How do i combine multiple cells into one

I have 3 cells each containting three 20x60 matrices

cell_1 = { 20x60, 20x60 , 20x60 }

...

cell_3= { 20x60, 20x60 , 20x60 }

I would like to stack them on top of each other

cell_1

cell_2

cell_3

so that i obtain final_cell =3 x 3 cell

c1 = {rand(2), rand(2)}

c1 = 1×2 cell array
    {2×2 double}    {2×2 double}

c2 = {rand(2), rand(2)}

c2 = 1×2 cell array
    {2×2 double}    {2×2 double}

c3 = {rand(2), rand(2)}

c3 = 1×2 cell array
    {2×2 double}    {2×2 double}

c =[c1; c2; c3]

c = 3×2 cell array
    {2×2 double}    {2×2 double}
    {2×2 double}    {2×2 double}
    {2×2 double}    {2×2 double}

ok never mind figured it out

final_cell=[cel_1; cell_2; cell_3]
