Matrix A is 1000*1000 in size. I want to make normal PDF of each row( for example A(1,1:1000) and then A(2,1:1000) and...), by normpdf(A,mean(A),std(A)) function.
can you please advise?
thank you

% Made up some pretend data
N = 1000;
A = randn(N);
% Preallocate memory for the pdfs
Y = zeros(N);
% Calculate the pdfs
for nr = 1:N
Y(nr,:) = normpdf(A(nr,:),mean(A(nr,:)),std(A(nr,:)));
end
