de = ry; %//热源段在z坐标轴上的大 dee = abs(de - js); %//热源段与计算点的轴向距离 Sz = sqrt(r*r + dee * dee); %// r = sqrt(pow((xip - x), 2) + pow((yiq - y), 2));计算点到热源段的距离 d0 = log(lamdpor(1)); d1 = log(lamdpor(2)); d2 = log(lamdpor(3)); d3 = log(lamdpor(4)); if (jjz == 1 && jji == 1) elseif (jjz == 1 && jji == 2) elseif (jjz == 1 && jji == 3) elseif (jjz == 1 && jji == 4) elseif (jjz == 2 && jji == 1) elseif (jjz == 2 && jji == 2) elseif (jjz == 2 && jji == 3) elseif (jjz == 2 && jji == 4) elseif (jjz == 3 && jji == 1) elseif (jjz == 3 && jji == 2) elseif (jjz == 3 && jji == 3) elseif (jjz == 3 && jji == 4) elseif (jjz == 4 && jji == 1) elseif (jjz == 4 && jji == 2) elseif (jjz == 4 && jji == 3) elseif (jjz == 4 && jji == 4) end de = ry; dee = abs(de + js); Sz = sqrt(r*r + dee * dee); d0 = log(lamdpor(1)); d1 = log(lamdpor(2)); d2 = log(lamdpor(3)); d3 = log(lamdpor(4)); if (jjz == 1 && jji == 1) elseif (jjz == 1 && jji == 2) elseif (jjz == 1 && jji == 3) elseif (jjz == 1 && jji == 4) elseif (jjz == 2 && jji == 1) elseif (jjz == 2 && jji == 2) elseif (jjz == 2 && jji == 3) elseif (jjz == 2 && jji == 4) elseif (jjz == 3 && jji == 1) elseif (jjz == 3 && jji == 2) elseif (jjz == 3 && jji == 3) elseif (jjz == 3 && jji == 4) elseif (jjz == 4 && jji == 1) elseif (jjz == 4 && jji == 2) elseif (jjz == 4 && jji == 3) elseif (jjz == 4 && jji == 4) end优化代码

可以将重复的代码提取为函数，将不同的参数作为函数的输入，以减少代码冗余。例如：

function Sz = calculateSz(x, y, z, ry, js, r, lamdpor, jjz, jji)
    de = ry;
    dee = abs(de - js);
    if z < 0
        dee = abs(de + js);
    end
    Sz = sqrt(r*r + dee*dee);

    d = log(lamdpor);
    d0 = d(1);
    d1 = d(2);
    d2 = d(3);
    d3 = d(4);

    if jjz == 1 && jji == 1
        % do something
    elseif jjz == 1 && jji == 2
        % do something
    % ... 省略部分代码
    elseif jjz == 4 && jji == 3
        % do something
    elseif jjz == 4 && jji == 4
        % do something
    end
end

然后在主函数中调用该函数即可，例如：

Sz = calculateSz(x, y, z, ry, js, r, lamdpor, jjz, jji);

openpyxl将2024/9/16保存为时间格式%Y/%m/%d

OpenPyXL是一个用于读写Excel 2010 xlsx/xlsm/xltx/xltm文件的库，它主要用于操作电子表格，而不是直接处理日期字符串转换。如果你想将特定的日期字符串 "2024/9/16" 转换为 `%Y/%m/%d` 格式的时间，可以使用Python内置的 `datetime` 模块。下面是一个示例：

from datetime import datetime

date_str = "2024/9/16"
format_str = "%Y/%m/%d"

# 将字符串转换为datetime对象
date_format = datetime.strptime(date_str, '%Y/%m/%d')

# 再将datetime对象格式化为所需的格式
formatted_date = date_format.strftime(format_str)

print(formatted_date)

当你运行这段代码，它会打印出 "2024/09/16"，这就是 `%Y/%m/%d` 格式下的日期。

如果你要在OpenPyXL中设置单元格的时间格式，可以这样做：

import openpyxl
from openpyxl.styles import PatternFill

# 创建或打开工作簿
workbook = openpyxl.load_workbook('example.xlsx')
worksheet = workbook.active

# 假设A1单元格存储着你的日期字符串
cell_value = "2024/9/16"
cell = worksheet['A1']
cell.value = formatted_date

# 设置单元格的日期格式
cell.number_format = format_str

# 或者更简洁的方式，直接设置格式然后写入值
cell.cell_style = openpyxl.styles.borders.BORDER_THIN
cell.fill = PatternFill(start_color='D7DEE3', end_color='D7DEE3', fill_type=openpyxl.styles.PatternFill.FILL_SOLID)
cell.font = openpyxl.styles.Font(bold=True)
cell.alignment = openpyxl.styles.Alignment(horizontal='center', vertical='center')
cell.value = formatted_date

这会在A1单元格显示 "2024/09/16" 并设置为相应的日期格式。

de = ry; dee = abs(de - js); Sz = sqrt(r*r + dee * dee); d0 = log(lamdpor(1)); d1 = log(lamdpor(2)); d2 = log(lamdpor(3)); d3 = log(lamdpor(4)); if (jjz == 1 && jji == 1) elseif (jjz == 1 && jji == 2) elseif (jjz == 1 && jji == 3) elseif (jjz == 1 && jji == 4) elseif (jjz == 2 && jji == 1) elseif (jjz == 2 && jji == 2) elseif (jjz == 2 && jji == 3) elseif (jjz == 2 && jji == 4) elseif (jjz == 3 && jji == 1) elseif (jjz == 3 && jji == 2) elseif (jjz == 3 && jji == 3) elseif (jjz == 3 && jji == 4) elseif (jjz == 4 && jji == 1) elseif (jjz == 4 && jji == 2) elseif (jjz == 4 && jji == 3) elseif (jjz == 4 && jji == 4) end de = ry; dee = abs(de + js); Sz = sqrt(r*r + dee * dee); d0 = log(lamdpor(1)); d1 = log(lamdpor(2)); d2 = log(lamdpor(3)); d3 = log(lamdpor(4)); if (jjz == 1 && jji == 1) elseif (jjz == 1 && jji == 2) elseif (jjz == 1 && jji == 3) elseif (jjz == 1 && jji == 4) elseif (jjz == 2 && jji == 1) elseif (jjz == 2 && jji == 2) elseif (jjz == 2 && jji == 3) elseif (jjz == 2 && jji == 4) elseif (jjz == 3 && jji == 1) elseif (jjz == 3 && jji == 2) elseif (jjz == 3 && jji == 3) elseif (jjz == 3 && jji == 4) elseif (jjz == 4 && jji == 1) elseif (jjz == 4 && jji == 2) elseif (jjz == 4 && jji == 3) elseif (jjz == 4 && jji == 4) end

这段代码中有大量的重复代码，并且if-elseif结构也非常冗长。可以将重复的代码提取为函数，将不同的参数作为函数的输入，以减少代码冗余。例如：

function [Sz, d0, d1, d2, d3] = calculateDistanceAndLog(x, y, z, ry, js, r, lamdpor, jjz, jji)
    if z >= 0
        de = ry;
        dee = abs(de - js);
    else
        de = ry;
        dee = abs(de + js);
    end
    Sz = sqrt(r*r + dee*dee);

    d = log(lamdpor);
    d0 = d(1);
    d1 = d(2);
    d2 = d(3);
    d3 = d(4);
end

然后在主函数中调用该函数即可，例如：

[Sz, d0, d1, d2, d3] = calculateDistanceAndLog(x, y, z, ry, js, r, lamdpor, jjz, jji);
if jjz == 1 && jji == 1
    % do something
elseif jjz == 1 && jji == 2
    % do something
% ... 省略部分代码
elseif jjz == 4 && jji == 3
    % do something
elseif jjz == 4 && jji == 4
    % do something
end

这样可以使代码更加简洁易读。
