put each column of a matrix into different cells

I have a matrix of size (4x4)

a = [1 2 3 4; 123 4 5 6; 52 5 4 7; 2 5 8 7];
b = mat2cell(a, ?)

I want b to be a {4x1} or {1x4} cell where every cell contains the column values of matrix

b = cell{1,:} = [1; 123; 52; 2] , cell{2,:} = [2 ; 4 ; 5 ; 5] and so on. but i am not being able to figure out mat2cell input parameters

Use num2cell. it is easy

a = [1 2 3 4; 123 4 5 6; 52 5 4 7; 2 5 8 7];
b = num2cell(a,1)

b =

1×4 cell array

{4×1 double} {4×1 double} {4×1 double} {4×1 double}

mat2cell

is usefulll for other purpose

b = mat2cell(a.',[1 1 1 1])

b =

1×4 cell array

{4×1 double} {4×1 double} {4×1 double} {4×1 double}
