I am using tensorflow 0.9. when I am trying to calculate a simple l1-norm of vector, like matrix = vs.get_variable("Matrix", [total_arg_size, output_size]) l1norm = tf.reduce_mean(tf.abs(matrix)) Tensorflow allocates memory for the resul...
n = quatnorm(q) Description n = quatnorm(q) calculates the norm, n, for a given quaternion, q. Input q is an m-by-4 matrix containing m quaternions. n returns a column vector of m norms. Each element of q must be a real number. Aerospace Toolbox uses quaternions that are defin...
The determinant, Δ ⊥ , of the map is | B R c a l B R S | . The matrix G ⊥ ∗ is R S 2 [ sin 2 θ R S 0 0 1 ] The matrix G ⊥ is R c a l − 2 [ sin − 2 ( θ R c a l ) 0 0 1 + B θ , R c a l 2 B r , R c a l 2...
Computer code In the following, we use bold font to represent the finite-dimensional vectors and matrixes. Let be the matrix such that We can assemble to formulate the corresponding matrix and where is the test function, is finite-dimensional approximation of the function Here, is a small numbe...
A dimension of V , dim(V ), is the number of vectors in a basis range就是是一个function 所有可能输出的集合,比如一个matrix A 如果用一个vector v乘的话 Av=w, w就相当于输出啦 A就可以看作是一个function A的column space就是A所代表的function的 range,假设有一个matrix A是n * m,那么matri...
