The resulting column Z is filled according to the conditions and formulas:
If the condition1 [S1+S2>10] and the condition2 [S1*D>k/6-30] are met
Z = D, otherwise Z = empty
where S1, S2, D is the value of the corresponding columns, k is the coefficient.How it should look in the ideal (screen):

Есть массив данных, файл .csv. Состоит из нескольких столбцов c произвольными названиями латиницей. Количество строк 500к+.
В результате необходимо рассчитать и дописать в файл еще три столбца.
Столбец S1, cкользящая средняя значений столбца D, выборка за N1 строк
Столбец S2, cкользящая средняя значений столбца D, выборка за N2 строк
Результирующий столбец Z, заполняется по условиям и формулам:
Если условие1 [S1+S2>10] И условие2 [S1*D>k/6-30] соблюдаются
то Z=D, иначе Z=пусто
где S1,S2,D - значение соответствующих столбцов, k - коэффициент.
Диапазон значений N1 и N2 - до 2000
Как это должно выглядеть в идеале (скрин):
_____________
Диалоговое окно с выбором файла.
Окно ввода значений N1=[ ], N2=[ ], k=[ ]
Окно присвоения переменных столбцам: [название столбца] = [переменная]
Опционно:
Окно ввода значений условия1: [левая часть] [знак <>=] [правая часть]
Окно ввода значений условия2: [оператор перед условием2: И/ИЛИ] [левая часть] [знак <>=] [правая часть]
Окно ввода значений условия3: [учитывать ли условие] [оператор перед условием3: И/ИЛИ] [левая часть] [знак <>=] [правая часть]
Окно ввода значений условия4: [учитывать ли условие] [оператор перед условием4: И/ИЛИ] [левая часть] [знак <>=] [правая часть]
- формулы 3 и 4 будут учитываться в отдельных случаях, в основном учитываются формулы 1 и 2, галочка выбора
- в левой и правой части условий можно указывать: цифры, скобки, знаки (+-/*) и значения столбцов в виде переменных (S1, S2, A,B,C,D,E)
- знак между частями: <, >, >=, <=
кнопка "Заполнить"
________________
Это идеальный вариант. По умолчанию рассматриваем базовый вариант.
В базовом варианте условия можно редактировать и дополнять в коде - не проблема, это делается редко.
Цель задания: После введения значений N1, N2, k и названий переменных столбцов, нажатия кнопки "Заполнить" система рассчитывает и записывает данные в столбцы S1, S2, Z.
Основное требование: выполнение вычислений и заполнения файла с 500к строк в течении нескольких (2-3) минут, очень желательно одной минуты.
Как должна работать система: файл предназначен для другой программы, в ней идет визуализация данных и анализ. После анализа корректируются N1, N2, k, после файл пересчитывается, перезаписывается, подгружается и снова визуализация и анализ. И так циклически много раз. Поэтому кроме того что быстро, должно быть удобно.
Проект интересует в базе. Но если опционная часть не сильно удорожит, то тоже нужно.
Язык написания не принципиален.
Уточнил диапазон значений и описание работы системы, но машинально скопировал все.
