Study Notes
NumPy Data Structure
- The main data structure provided by NumPy for numerical computing is the multidimensional array.
NumPy Operations
- NumPy allows element-wise operations on entire arrays of data, such as basic arithmetic, bitwise, and comparison operations.
- NumPy also allows matrix operations, including matrix multiplication and matrix exponentiation.
Additional Operations
- NumPy provides operations in addition to array-oriented arithmetic, including sorting, indexing, and reshaping of arrays.
- NumPy also provides functions for tasks such as linear algebra, Fourier transform, and random number generation.
Internal Data Storage
- NumPy internally stores data in a contiguous block of memory, allowing for efficient computation and manipulation of data.
Benefiting Packages
- Several Python packages benefit from NumPy as a computational foundation, including SciPy, Matplotlib, and Pandas, among others.
