* Old Code Would Not Compile
I researched the Chrono library and made sure the code would compile with the latest Rust 2018 setup.
* Remove the DateTime part for the chrono piece
* Removed Chrono to simplify example
* added invert-matrix to /science/mathematics/linear_algebra
* added nalgebra as dependency
* added nalgebra to dictionary
* fixed link to nalgebra
* Remove statistics file only includes the header
* sqlite transactions recipe
* Reordered/cleaned-up references
* Removed package version from links
* Updates after review
* Removed comment
* Taking out a pronoun
* added Text Processing > String Parsing > Implement the FromStr trait for a custom struct
* Implement the FromStr trait for a custom struct
* fixed formatting
* fixed formatting
* Update crossbeam-spawn.md
In the latest version od Crossbeam ([docs](https://docs.rs/crossbeam/0.5.0/crossbeam/)) we have two changes:
1. Spawned closures take an argument of type `&Scope` which can be used for nested spawns.
2. The `scope` function returns a `Result` indicating whether spawned threads have been joined with success or not.
Updating the example accordingly.
* Return option from find_max
* Use split_at
* Add Statistics Section With Examples
Add a statistics section to the cookbook!
Add an example showing how to calculate mean, median, and mode using the
Rust standard library.
Add a second example showing how to compute the standard deviation and zscore
of a set of data.
* Seek Brevity, Improve Median Example
Shorten some of the example descriptions, preferring to let the code and
Rust documentation speak for itself.
Calculate the median using an adaptation of the quickselect algorithm,
which does not mutate the original data set and should (in theory) be
slightly more performant.
Remove the unneeded statistics summary file
The CSV encoding tab delimiter example has a struct to deserialize into.
However it wasn't used.
I've changed it to use the provided struct.
It may make more sense to remove it instead, as it isn't the point of
this example. If it turns out to be the preferred method in the pull
request process, I'll do so.
Two link targets for web client download examples have been swapped, revert them. And also remove a dot at the end of a heading in one of the examples.
The original version was incorrect about `ndarray`'s treatment of 1-D
arrays as vectors, and it incorrectly indicated that `*` performed
matrix multiplication.
`ndarray` decides whether a 1-D array is a row vector or column vector
in matrix multiplication by whether it is on the left-hand side or
right-hand side. (The behavior matches NumPy. If it's on the left-hand
side, it's a row vector, while if it's on the right-hand side, it's a
column vector.) The original version incorrectly indicated that
calling `.reversed_axes()` on a 1-D array would make it into a column
vector. In fact, calling `.reversed_axes()` on a 1-D array has no
effect since a 1-D array has only 1 axis.
Matrix multiplication is performed with `.dot()`, not `*`. The `*`
operator performs element-wise multiplication.
This removes an unnecessary allocation caused by `.mapv()` in the
original version, replaces `&Array1<f64>` argument types with
`ArrayView1<f64>` (see the new text for reasoning), and takes
advantage of the `array!` macro to make the array creation more
concise.
Part of tracking issue #450.
Once #452 is merged I will rebase and add appropriate section links.
Similarly, once #463 is merged I will update badge links.
