Divided a matrix into sub-matrices (MATLAB)

Dear members;

I have an empty matrix of dimensions (m*n)=(6*12) using:

H=zeros(m,n)

I have to fil this matrix with ones, in order to obtain J=3 ones in each column and K=6 ones in each row.

J=3; K=6;

Firstly, I want to divise this matrix H into J sub-matrices, each sub-matrix contains (n/K) rows and a nonzero element in each column.

Can anyone help me to program this step please

Answer 1

[KSSV]

H=zeros(m,n) ; 
J = 3 ; K = 6 ;
H(:,J) = 1 ;
H(K,:) = 1 ;

@KSSV Sorry, but that's not what I search for.

Using your code, I dont get the condition that I want ( I want to divise this matrix H into J sub-matrices, each sub-matrix contains (n/K) rows and a nonzero element in each column)

Are you sure about that? n is the number of columns, not the number of rows. It would seem to me to make more sense to divide into J sub-matrices each containing m/J rows.

m = 6; n = 12;
J=3; K=6;

H=zeros(m,n)

H = 6×12

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

split = mat2cell(H, (n/K) * ones(1,m*K/n), n)

split = 3×1 cell array
    {2×12 double}
    {2×12 double}
    {2×12 double}

Not sure where you want to go from there.
