matrix value propagation along the rows

Hello,

A(1,1:7) vector and I want a mtrix where A is repeated in B matrix 19 rows B(1:19,1:7).

Matlab sims to have issues with B(1:19,:)=A, or B(1:19,1:7)=A.

So idea is A = [1 2 3 4 5 6 7]

and resulting

B = [

1 2 3 4 5 6 7

1 2 3 4 5 6 7

1 2 3 4 5 6 7

...

] (in 19 rows)

Any of these should do

A = [1 2 3 4 5 6 7]

A = 1×7

1 2 3 4 5 6 7

B(1:19,1:7)=repmat(A,19,1)

B = 19×7

1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7

B(1:19,1:7)=repelem(A,19,1)

B = 19×7

1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7

B(1:19,1:7)=A(ones(1,19),:)

B = 19×7

1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7

for r=1:19
    B(r,:) = A;
end
B

B = 19×7

1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7

A = [1 2 3 4 5 6 7];
B = repmat(A,[19,1])

B = 19×7

1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7
