Good day,
I am having little trouble with Octave.
Description:
On octave I get following error when multiply tow moving indexes.
octave:103> x=[0 2 3 4 5 6 7 8 9]
x =
0 2 3 4 5 6 7 8 9
octave:105> sin(x)*cos(x)
error: operator *: nonconformant arguments (op1 is 1x9, op2 is 1x9)
octave:106>
While on wolframalpha.com I get nice function:
sin(x)cos(2x); x=[0 to 9]
You need to use ".*" instead of "*". The former is the pointwise multiplication, the latter is the vector/matrix/tensor multiplication.
