Initial release of the einsum
R package.
Features:
einsum()
: execute complex array multiplications using a concise and unambiguous based on the Einstein notation ("abc, b, c -> ac"
).einsum_generator()
: generate an efficient C++ function that can be used for repeatedly executing the same
multiplication. It can also produce the source code for a C++ function which you can integrate into your own package.Thanks to @kokitsuyuzaki for helping me push this over the finish line and the numpy project for their equivalent function that inspired this package.
Add the following code to your website.
