01. Scipy Tutorial-简要介绍
Scipy是Python世界里比较知名的算法、运算相关的模块包，多数功能基于Numpy扩展而成。在ubuntu系统上，Scipy安装后的目录/usr/local/lib/python2.7/dist-packages/scipy。
- Scipy其重要组成部分的各个子包如下：
| Sicpy包含的子包 | 功能 |
|---|---|
| cluster | --- Vector Quantization / Kmeans |
| fftpack | --- Discrete Fourier |
| integrate | --- Integration routines |
| interpolate | --- Interpolation Tools |
| io | --- Data input and output |
| lib | --- Python wrappers to |
| lib.lapack | --- Wrappers to LAPACK library |
| linalg | --- Linear algebra routines |
| misc | --- Various utilities that don't have another home. |
| ndimage | --- n-dimensional image package |
| odr | --- Orthogonal Distance Regression |
| optimize | --- Optimization Tools |
| signal | --- Signal Processing Tools |
| sparse | --- Sparse Matrices |
| sparse.linalg | --- Sparse Linear Algebra |
| sparse.linalg.dsolve | --- Linear Solvers |
| sparse.linalg.dsolve.umfpack | --- :Interface to the UMFPACK library |
| sparse.linalg.eigen.lobpcg | --- Locally Optimal Block Preconditioned |
| special | --- Airy Functions [*] |
| lib.blas | --- Wrappers to BLAS library [*] |
| sparse.linalg.eigen | --- Sparse Eigenvalue Solvers [*] |

- 查帮助 1) 用help和dir来查某包下的某函数模块的帮助 2)用numpy的info来查看scipy相关内容的帮助。
>>> import numpy as np
>>> np.info(scipy.linalg)
