根据最后一列的值分割行并将其保存到其他文件中

Question

我有一个包含9列的txt文件，最后一列是0或1。我想根据最后一列的值将它们保存到其他txt文件中。如何使用matlab做到这一点？

txt文件

43 34 6 8 2 6 2 3 0

23 54 2 5 8 2 61 6 1

46 4 6 8 23 6 2 3 0

3 5 2 75 48 23 1 6 0

3 54 23 5 58 2 1 6 1

46 4 67 8 3 6 24 23 0

32 5 2 75 98 23 1 6 1

Answer 1

我假设您知道如何将矩阵保存到文件，但不知道拆分矩阵的方法。

在这里，我只提供一种解决方案，可以帮助您根据最后一列拆分矩阵：

$('#btnEditImageSave').unbind().click(function (event) {
        $('#progressBardiv').css('width', '0');
        $('.progressBardiv').text('');  
 if (uploadedfiles.length > 0 && deleteFiles.length == 0) {
                if (editStoredFiles.length > 0) {
                    var files = new FormData();
                    for (var i = 0; i < editStoredFiles.length; i++) {
                        if (editStoredFiles[i].size > 0) {
                            files.append(editStoredFiles[i].name, editStoredFiles[i]);
                        }
                    }
                    uploadedfiles = [];
                    files.append('SerialNumber', editSerialNumber);
                  $.ajax({
                        type: "POST",
                        url: productionBaseUrl + '/Home/UploadDockingStationFiles',
                        data: files,
                        contentType: false,
                        processData: false,
                      async: true,

                      complete: function () {
                          uploadedfiles = [];
                          $('#editfileupload').val();
                          $.ajax({
                                type: "POST",
                                url: cloudServerUrl + "/api/dockstation/updatefiledisplaytimer",
                                contentType: "application/json; charset=utf-8",
                                dataType: "json",
                                data: JSON.stringify({
                                    SerialNumber: $('#ddlEditDockingStationSerialNumber').val(),
                                    FileSpinTimer: $('#txtEditTimer').val(),
                                    IsHDMIUpdate: isHDMIUpdate
                                }),
                               /*----My Progress Bar code----*/
                                xhr: function () {
                                    var xhr = new window.XMLHttpRequest();
                                    xhr.upload.addEventListener("progress", function (event) {
                                        if (event.lengthComputable) {
                                            var percentComplete = event.loaded / event.total;
                                            percentComplete = parseInt(percentComplete * 100);
                                            $('#progressBardiv').text(percentComplete + '%');
                                            $('#progressBardiv').css('width', percentComplete + '%');
                                        }
                                    }, false);
                                    return xhr;
                                },
                                complete: function () {
                                    $('#loading-popup').hide();
                                    $('#divEditDockingStationImages').dialog("close");
                                    $.popup('<pre>Message</pre>', "Image Configuration Updated Successfully.", 'OK');
                                    return false;
                                }
                            });
                        }
                    });
                }
            }
            else {
                $('#loading-popup').hide();
                $.popup('<pre>Message</pre>', "Please Select a File.", 'OK');
                return false;
            }
}


    <div class="progress">
     <div id="progressBardiv" class="progress-bar" role="progressbar" aria-valuemin="0" aria-valuemax="100" style="">
     <span class="sr-only"></span>
     </div>
     </div>

然后，您可以将矩阵% ending with 0 in each row m0 = m(find(m(:,end)==0),:); >> m0 m0 = 43 34 6 8 2 6 2 3 0 46 4 6 8 23 6 2 3 0 3 5 2 75 48 23 1 6 0 46 4 67 8 3 6 24 23 0 % ending with 1 in each row m1 = m(find(m(:,end)),:); >> m1 m1 = 23 54 2 5 8 2 61 6 1 3 54 23 5 58 2 1 6 1 32 5 2 75 98 23 1 6 1 和m0保存在不同的.txt文件中，例如m1和dlmwrite('m0.txt',m0)

数据

dlmwrite('m1.txt',m1)
