kandi X-RAY | kindr Summary

kindr is a C++ library typically used in Automation, Robotics applications. kindr has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Simplified header include #include is provided. Kindr is now strongly dependent on Eigen. All sub namespaces have been removed. (e.g. kindr::rotations::eigen_impl → kindr::). The implementations of rotations and time derivatives have been simplified (Passive, Hamiltonian). Conversion methods between ROS and kindr have been moved to the package [kindr_ros] Concatenation of Homogeneous Transformation is now implemented. Short typedefs are provided for Homogeneous Transformation: HomTransformQuatD, HomTransformMatrixD. Jacobian of exponential map is implemented. Unit tests based on gtest are provided to test the convention of other software packages.

Unnesting elements of large list into dataframe

Asked 2021-Oct-26 at 14:44

I am currently working with a large dataset I retrieved from the crossref API in which I retrieved information on scientific papers based on a DOI search.

Currently the large list contains of ~3500 elements. Each of these elements is a list of their own consisting of the metadata 'meta', the actual relevant data 'data' and an irrelevant list 'facets'.

This is an example of two of the lists based on two DOI's:

Like this? Note - it is better to include a Minimal reprex that includes a toy data set, rather than a snapshot of what you have. This way the question will likely get answers faster.

QUESTION

Quaternion division not equal to multiplication with inverse (q1 / q2 != q1 * q2^-1)?

Asked 2021-Aug-09 at 13:10

From several docs, like [1] and [2], I learned that divide operation on a quaternion is equivalent to multiply its inverse. That is to say, for two quaternions q1 and q2, we have

However, when I verify this in MATLAB, which will give different results (also verified by further converting them to rotation matrix via quat2rotm). See code below:

Note that quaternion division leads to an ambiguous notation.

reading from your 2nd reference it states

To expand upon this see what the result of the two interpretations are:

They differ by the sign of the cross product in the vector part.

I suspect that quatdivide() uses the 2nd convention such as

I am loading a google spreadsheet via tabletop.js and when the user types in the title of a book, the script is supposed to print out the author of the book. So if you type in "Kindred" it is supposed to return "Octavia Butler". I can't figure out how I can access the author by passing in the title.

Not really a DataTable question but fun, and I'm bored witless ;-)

The URL you posted is correct and you had it commented out in the CodePen, I don't use it so I've posted the corrected version on JSFiddle here. You were nearly there but you needed to check the searching function you were trying, that would've worked with types of data but not the one you were using. You needed to search through the objects returned for a value and then return a different value from the found object.

You also had two methods kicking off once when the DOM was loaded, so I've removed one.
