文本文件的 3d 到 2d 转换并在 matlab 中自动粘贴/加载 .m 文件
3d to 2d conversion of text files and autmatically pasting /loading .m file in matlab
更新 1:
我在文本文件中有 GP_Height 数据。此文本文件包含 3D 数组。其完整描述如fellow
[t][x][y]，值 1，值 2，.....，值 8
(1) [t]是文本文件中保留[0]的时间
(2) [x] is pressure level index variable [0] to [16] : 对应的压力等级是 [1000.0, 925.0, 850.0, 700.0 , 600.0, 500.0, 400.0, 300.0, 250.0, 200.0, 150.0, 100.0, 70.0, 50.0, 30.0, 20.0, 10.0]
(3) [y]是从[0]到[8]的纬度指数：对应的纬度指数是[37.5, 35.0, 32.5, 30.0, 27.5, 25.0, 22.5, 20.0]
(4) Value1,value2...value8 :是经度索引[60.0, 62.5, 65.0, 67.5, 70.0, 72.5, 75.0, 77.5]对应的GP_height值
现在
[0][0][0] , value1,.... ,value8 是tGP_height的8个值，对应时间0，气压1000，纬度20.0，对应经度指数。
很快就会出现这种模式
我想导出 17 个带有 output_no.txt 的文本文件（其中 no 是从 0 到 16），这样第一列是纬度，第二列是经度，第三列包含 GP_height 值这个纬度，经度
我试试这个，但不确定发生了什么。（产生错误的输出。缺少 GP_height）
pressures = [1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20, 15, 10, 7, 5, 3, 2, 1.5, 1] ;
% - Read source file.
fSpec = ['[%f][%f][%f]', repmat( ', %f', 1, 8 )] ;
data = textscan( fileread( 'modified.New Text Document.txt' ), fSpec ) ;
%New Text Document
% - Extract/gather all x and gp values.
X = data{1} ;
GP = horzcat( data{3:end} ) ;
% - Build arrays of lon/lat which correspond to GP.
[lon, lat] = meshgrid( 60:2.5:77.5, 20:2.5:37.5) ;
% - Iterate through pressure IDs and process.
for x = 0 : 23
% Get relevant block of GP (the one thta corresponds to current p).
gp = GP(X==x,:) ;
% Build 3 columns data array.
data = [reshape(lat.',[],1), reshape(lon.',[],1), reshape(gp.',[],1)].' ;
% Verbose.
fprintf( 'Export for pressure ID %d -> p=%.1fhpa.\n', x, pressures(x+1) ) ;
% Export.
fId = fopen( sprintf( 'Output_%d.txt', x), 'w' ) ;
fprintf( fId, 'latitude\tlongitude\tGP_height\r\n' ) ;
fprintf( fId, '%.3f\t%.3f\t%.3f\r\n', data(:) ) ;
fclose( fId ) ;
end
我在文本文件中的数据看起来像这样

我已将此代码作为 sorted_lat_split.m 保存到地址
的驱动器中
E:\meta data\new\data _thesis\NCEP\winds_speed
在winds_speed文件夹中还有30个文件夹并且在这30个文件夹中的每个文件夹中都有里面有12个文件夹。我想在每个 'sorted_lat_split.m' 文件夹 中传递这个 'sorted_lat_split.m' 文件，并想在每个文件夹中 运行 这个文件。
告诉我是否可以粘贴此代码以节省我的时间？
请帮忙！
另一个解析问题，这个更容易，因为你有分隔符，你需要做的第一件事是取出第一列（我将其命名为 C1），其中包含你需要查找的 3 个索引：
fileID = fopen('test1.txt')
C = textscan(fileID,'%s %f %f %f %f %f %f %f %f','delimiter',',');
parseC1 = cell2mat(cellfun(@(s)sscanf(s,'[%d]'),C{1},'UniformOutput',false));
reshapeC1 = reshape(parseC1,3,size(parseC1,1)/3)' +1; %//PLUS 1 because matlab indexing starts at 1 NOT 0
现在这会将 C1 生成为 N 乘以 3 的矩阵，其中 N 是总行数。
这将使您可以轻松匹配压力和温度向量，最后一步只是将矩阵与 8 值矩阵连接起来：
readVec = [pressures(reshapeC1(:,2)); latt(reshapeC1(:,3))]'
Values = [C{2} C{3} C{4} C{5} C{6} C{7} C{8} C{9}];
LongtValues = longt(round(Values))
FinalResult = [readVec LongtValues];
显示第一行给出：
>> 1000 37.5000000000000 67.5000000000000 70 67.5000000000000 65 62.5000000000000 62.5000000000000 62.5000000000000 62.5000000000000
对应气压1000，纬度37.5，经度8。由于我不确定你从哪里获得温度，以及你想如何将经度和纬度格式化为 table，我无法继续进行。
restructure = repmat(FinalResult(:,2),1,size(FinalResult,2)-2)'
Result = [restructure(:) LongtValues(:)]
此行给出您指定的经度和纬度读数：
>>Result = 37.5 67.5
37.5 72.5
37.5 77.5
.....
注意 reshapeC1，因为我将 1 添加到所有索引，因为 Matlab 索引从 1 而不是 0 开始（与大多数其他语言一样）。我对此进行了测试，它可以很好地解析你的所有行。
更新 1:
我在文本文件中有 GP_Height 数据。此文本文件包含 3D 数组。其完整描述如fellow
[t][x][y]，值 1，值 2，.....，值 8
(1) [t]是文本文件中保留[0]的时间
(2) [x] is pressure level index variable [0] to [16] : 对应的压力等级是 [1000.0, 925.0, 850.0, 700.0 , 600.0, 500.0, 400.0, 300.0, 250.0, 200.0, 150.0, 100.0, 70.0, 50.0, 30.0, 20.0, 10.0]
(3) [y]是从[0]到[8]的纬度指数：对应的纬度指数是[37.5, 35.0, 32.5, 30.0, 27.5, 25.0, 22.5, 20.0]
(4) Value1,value2...value8 :是经度索引[60.0, 62.5, 65.0, 67.5, 70.0, 72.5, 75.0, 77.5]对应的GP_height值
现在
[0][0][0] , value1,.... ,value8 是tGP_height的8个值，对应时间0，气压1000，纬度20.0，对应经度指数。
很快就会出现这种模式
我想导出 17 个带有 output_no.txt 的文本文件（其中 no 是从 0 到 16），这样第一列是纬度，第二列是经度，第三列包含 GP_height 值这个纬度，经度
我试试这个，但不确定发生了什么。（产生错误的输出。缺少 GP_height）
pressures = [1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20, 15, 10, 7, 5, 3, 2, 1.5, 1] ;

我已将此代码作为 sorted_lat_split.m 保存到地址
的驱动器中E:\meta data\new\data _thesis\NCEP\winds_speed
在winds_speed文件夹中还有30个文件夹并且在这30个文件夹中的每个文件夹中都有里面有12个文件夹。我想在每个 'sorted_lat_split.m' 文件夹 中传递这个 'sorted_lat_split.m' 文件，并想在每个文件夹中 运行 这个文件。
告诉我是否可以粘贴此代码以节省我的时间？
请帮忙！
另一个解析问题，这个更容易，因为你有分隔符，你需要做的第一件事是取出第一列（我将其命名为 C1），其中包含你需要查找的 3 个索引：
fileID = fopen('test1.txt')
C = textscan(fileID,'%s %f %f %f %f %f %f %f %f','delimiter',',');
parseC1 = cell2mat(cellfun(@(s)sscanf(s,'[%d]'),C{1},'UniformOutput',false));
reshapeC1 = reshape(parseC1,3,size(parseC1,1)/3)' +1; %//PLUS 1 because matlab indexing starts at 1 NOT 0
现在这会将 C1 生成为 N 乘以 3 的矩阵，其中 N 是总行数。
这将使您可以轻松匹配压力和温度向量，最后一步只是将矩阵与 8 值矩阵连接起来：
readVec = [pressures(reshapeC1(:,2)); latt(reshapeC1(:,3))]'
Values = [C{2} C{3} C{4} C{5} C{6} C{7} C{8} C{9}];
LongtValues = longt(round(Values))
FinalResult = [readVec LongtValues];
显示第一行给出：
>> 1000 37.5000000000000 67.5000000000000 70 67.5000000000000 65 62.5000000000000 62.5000000000000 62.5000000000000 62.5000000000000
对应气压1000，纬度37.5，经度8。由于我不确定你从哪里获得温度，以及你想如何将经度和纬度格式化为 table，我无法继续进行。
restructure = repmat(FinalResult(:,2),1,size(FinalResult,2)-2)'
Result = [restructure(:) LongtValues(:)]
此行给出您指定的经度和纬度读数：
>>Result = 37.5 67.5
37.5 72.5
37.5 77.5
.....
注意 reshapeC1，因为我将 1 添加到所有索引，因为 Matlab 索引从 1 而不是 0 开始（与大多数其他语言一样）。我对此进行了测试，它可以很好地解析你的所有行。
