vec_make

概要

This function calculates essential values required for executing the mat_maker.

It is intended to be used internally within mat_maker and is not designed for standalone use.

It has been separated from mat_maker to avoid making the function overly complex.

引数一覧

argument name	type	role
ele	str	A list of elements representing the matrix used in mat_maker
coflst	list(elements:int)	A list containing the coefficients applied to the matrix elements used in mat_maker

戻り値

app_lst（list）:

A list for storing the calculation results.

Each element is of type float.
