In NumPy you can writea*=2which doubles each element of arraya. C# doesn't have a*=operator and consequently overloading it in a Python fashion is not possible. This limitation is overcome by exposing inplace operator functions which all start with an 'i'. So duplicating all elements of...

Array-oriented(数组计算) computing in Python traces(追溯) its roots back to 1995, when Jim Hugunin created the Numeric library. (经历了)Over the next 10 yeras, many scientific programming communities began doing array programing in Python, but the library ecosystem(生态系统) had become fragmented...
