| 2 | +.. warning:: |
| 3 | + Since heavily importing into the global namespace may result in unexpected |
| 4 | + behavior, the use of pylab is strongly discouraged. Use `matplotlib.pyplot` |
| 5 | + instead. |
| 6 | +
|
| 7 | +`pylab` is a module that includes `matplotlib.pyplot`, `numpy`, `numpy.fft`, |
| 8 | +`numpy.linalg`, `numpy.random`, and some additional functions, all within |
| 9 | +a single namespace. Its original purpose was to mimic a MATLAB-like way |
| 10 | +of working by importing all functions into the global namespace. This is |
| 11 | +considered bad style nowadays. |
