I had a martix N*M matrix, I try to init matrix with an vector. I am doing with code which below.
signal=zeros(5,4);
vectorA=[1 2 3 4];
for k=1:5
signal(k,:)=vectorA;
end
Is there better way to a work this code ?

You can use repmat()
signal=zeros(5,4);
vectorA=[1 2 3 4];
for k=1:5
signal(k,:)=vectorA;
end
signal
y=repmat(vectorA,5,1)
