爱因斯坦求和约定是一种简化张量运算的表示方法,通过省略求和符号,使得张量运算的表达式更加简洁。NumPy 的einsum函数就是基于这一约定实现的,能够高效地进行各种张量操作。 Why Einsum?:为什么使用爱因斯坦求和约定。 Formal Definition:爱因斯坦求和约定的正式定义。
Once installed, the NumPy library can be added or connected to the Python codebase using the Pythonimportcommand such as: importnumpy Copy The module name ("numpy" in this case) can also be renamed through theimportcommand to make the module name more relevant, readable or easier to referenc...

Definition of NumPy Meshgrid In Python, meshgrid is a function that creates a rectangular grid out of 2 given 1-dimensional arrays that denote the Matrix or Cartesian indexing. MATLAB inspires it. This meshgrid function is provided by the module numpy. Coordinate matrices are returned from the co...
