Error vector magnitude (EVM) is a popular system-level performance metric that is defined in many communication standards, such as wireless local area networks (WLAN 802.11), mobile communications (4G LTE, 5G), and many more, as a compliance test. Beyond this, it is an extremely useful syst...
We will represent complex numbers in either cartesian or polar form as an array/list, using the first element as a type tag; the normal tags are "cart" (for cartesian) and "polar". The forms of the...

Birds are among the best-studied animal groups, but their prehistoric diversity is poorly known due to low fossilization potential. Hence, while many human-driven bird extinctions (i.e., extinctions caused directly by human activities such as hunting, as

You can check if a key is in the vocabulary like so:"cat" in vectorsYou can iterate through all keys and vectors like so:for key, vector in vectors: ...You can query for the vector of a key like so:vectors.query("cat")You can index for the n-th key and vector like so:...
