Element-wise matrix products between two lists.David Gerard
The Product block has two modes: Element-wise mode, which processes nonscalar inputs element by element, and Matrix mode, which processes nonscalar inputs as matrices. Element-Wise Mode When you set Multiplication to Element-wise(.*), the Product block is in Element-wise mode, in which it...
In this paper, we compare the matrix-based bounding and the element-wise bounding concerning the global optimization for the matrix product eigenvalues problem (MPEP), which addresses many typical bilinear matrix inequality problems for control synthesis. It is shown that using the matrix-based boundi...
For numpy.matrix objects, * performs matrix multiplication, and elementwise multiplication requires function syntax. 也就是说,当变量类型为 numpy.ndarray 时,∗表示的是Hadamard product;当变量类型为 numpy.matrix 时,∗表示的是matrix product。而LSTM源码中变量类型为 numpy.ndarray ,所以使用∗操作自然...
The multiplication of a matrixAby a matrixBto yield a matrixCis defined only when the number of columns of the first matrixAequals the number of rows of the second matrixB. To determine the elementcij, which is in theith row andjth column of the product, the first element in theith row...
are cell arrays, then how are they stored? Whole matrix in a single cell or each element in single cells?
When a scipy sparse matrix element-wise multiples a dense ndarray, the returned matrix is of type matrix, which seems very inefficient, given that it is obviously a sparse matrix. In [90]: A = scipy.sparse.csr_matrix((5, 5)) In [93]: B = np.random.randn(5, 5) In [96]: C ...

是一个element-wise函数(例如sigmoid函数),它作用于自变量矩阵/向量的每一项。因为element-wise函数针对矩阵的操作有别与矩阵乘法这类线性操作,我们不能像之前一样用Jacobian相乘的方式来获得这个函数 的梯度。 一个笨拙的方式思考一下,向量 变化 后使得
