Mastering SciPy

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

Any command-line input or output is written as follows:

In [7]: %time eigvals, v = spspla.eigsh(A, 5, which='SM')
CPU times: user 19.3 s, sys: 532 ms, total: 19.8 s
Wall time: 16.7 s
In [8]: print eigvals
[ 10.565523  10.663114  10.725135  10.752737  10.774503]
