% parameters for the neural network are "unrolled" into the vector % nn_params and need to be converted back into the weight matrices. % % The returned parameter grad should be a "unrolled" vector of the % partial derivatives of the neural network. % % Reshape nn_params back into the...
% S = MEAN(X) is the mean value of the elements in X if X is a vector. % For matrices, S is a row vector containing the mean value of each % column. % For N-D arrays, S is the mean value of the elements along the first % array dimension whose size does not equal 1. % ...
where v is the vector that defines the y-value for the vertical bar. Y-values can be non-monotonic, but cannot contain duplicate values. If z is a matrix, elements of z in the same row will appear in the same position on the y-axis. ...
In this article, we will explore the process of converting a vector into a skew-symmetric matrix using MATLAB. 1. Understanding Skew-Symmetric Matrices: A skew-symmetric matrix, A, is defined as a square matrix in which each element satisfies the property A(i,j) = -A(j,i). In other ...
