WebThe dot product is only defined for two vectors of the same type, so your expressions aT ⋅ a and a ⋅ aT are meaningless. However, because of the rules of matrix multiplication and the fact that a 1 × 1 matrix can be treated as a scalar, a ⋅ b = aTb. On the other hand, b ⋅ a ≠ baT, which is an n × n matrix. The correct expression is b ⋅ a = bTa. WebI am a longtime matlab user and somehow only now running into this issue that seems like strange behavior to me.

Here, u i are eigenvectors, and σ i are eigenvalues. Since σ 1 > σ 2 and for the most of the data component in the direction of x 1 is larger than the one in x 2, the coefficient before u 1 T is typically much larger than the one before u 2 T. This causes the points align with the first eigenvector mostly. 鮭ムニエルきのこレシピ人気
