Matrix multiplication
Run and explain the following:
A = randn(1000);
tic
for k = 1:10
C = A' * A;
end
toc
tic
for k = 1:10
C = A * A';
end
toc
tic
for k = 1:10
C = A * A;
end
toc
and the following
A = rand(1000);
B = rand(1000);
tic
for k = 1:10
C = A * B;
end
toc
A = single(A);
B = single(B);
tic
for k = 1:10
C = A * B;
end
toc
