Web18 mrt. 2024 · NumPy arrays are most commonly used to represent vectors or matrices of numbers. A 1-dimensional or a 1-D array is used for representing a vector and a 2-D array is used to define a matrix (where each row/column is a vector). These vectors and matrices have interesting mathematical properties. A vector, as we know it, is an entity in space. Web12 apr. 2024 · A Computer Science portal for geeks.
