MATLAB自动生成的函数可输入变量而不是.txt文件

如何解决MATLAB自动生成的函数可输入变量而不是.txt文件

MATALB的“导入数据”功能自动生成一个输入.txt文件并输出表的功能。此函数的前几行如下所示：

@RequestScope
class RequestContext {

  private String requestId;
  private String traceId; 
  private String authorisedId; 
  private String routeName; 
    
  // few more fields 

  @Inject RequestContext(SecurityContext securityContext) {
        this.requestId = UUID.randomUUID().toString();
        if(securityService.getAuthentication().isPresent()){
          this.authorisedId = (securityService
                              .getAuthentication().get()).getUserId().toString();
    }
  }
  
  /* to be updated in controller method interceptors */ 
  public void updateRouteName(String name){
      this.routeName = name; 
  }

但是，我需要此函数来输入变量，而不是将具有完全相同效果的.txt文件。我已经将所有数据以变量的形式存储在.txt文件中。我以为我可以简单地用变量替换using namespace sensor_msgs; using namespace std; void chatterCallback(const darknet_ros_3d_msgs::BoundingBoxes3d::ConstPtr& msg) { cout<<"Entering call back function" <<endl; int person_count = 0; int inc = 1; while (msg->bounding_boxes[0].Class == "person" ) { for(int count=0; count <= person_count; count++) { cout<<"Increment variable" << count <<endl; const std::string PLANNING_GROUP = "crane_control"; moveit::planning_interface::MoveGroupInterface move_group(PLANNING_GROUP); moveit::planning_interface::PlanningSceneInterface planning_scene_interface; string str= to_string(count); moveit_msgs::CollisionObject collision_object; collision_object.header.frame_id = "world"; collision_object.id = "BOX_person__" + str; cout<<"Person_BB:" << collision_object.id <<endl; shape_msgs::SolidPrimitive primitive; primitive.type = primitive.BOX; primitive.dimensions.resize(3); std::vector<float> array_xdim(inc); std::vector<float> array_ydim(inc); std::vector<float> array_zdim(inc); array_xdim[inc] = msg->bounding_boxes[0].xmax - msg->bounding_boxes[0].xmin; array_ydim[inc] = msg->bounding_boxes[0].ymax - msg->bounding_boxes[0].ymin; array_zdim[inc] = msg->bounding_boxes[0].zmax - msg->bounding_boxes[0].zmin; cout<<"dimx:" << array_xdim[inc] <<endl; cout<<"dimy:" << array_ydim[inc] <<endl; cout<<"dimz:" << array_zdim[inc] <<endl; primitive.dimensions[0] = array_xdim[inc]; primitive.dimensions[1] = array_ydim[inc]; primitive.dimensions[2] = array_zdim[inc]; geometry_msgs::Pose box_pose; std::vector<float> array_xpos(inc); std::vector<float> array_ypos(inc); std::vector<float> array_zpos(inc); array_xpos[inc] = (msg->bounding_boxes[0].xmax + msg->bounding_boxes[0].xmin)/2; array_ypos[inc] = (msg->bounding_boxes[0].ymax + msg->bounding_boxes[0].ymin)/2; array_zpos[inc] = (msg->bounding_boxes[0].zmax + msg->bounding_boxes[0].zmin)/2; box_pose.position.x = array_xpos[inc]; box_pose.position.y = array_ypos[inc]; box_pose.position.z = array_zpos[inc]; box_pose.orientation.w = 1.0; cout<<"position_x:" << box_pose.position.x <<endl; cout<<"position_y:" << box_pose.position.y <<endl; cout<<"position_z:" << box_pose.position.z <<endl; collision_object.primitives.push_back(primitive); collision_object.primitive_poses.push_back(box_pose); collision_object.operation = collision_object.ADD; std::vector<moveit_msgs::CollisionObject> collision_objects; collision_objects.push_back(collision_object); planning_scene_interface.applyCollisionObjects(collision_objects); cout<<"count:" << count <<endl; } inc++; person_count++; cout<<"Person count" << person_count <<endl; } cout<<"Exiting call back function" <<endl; } int main(int argc,char** argv) { ros::init(argc,argv,"cpp_subscriber"); ros::NodeHandle n; ros::Subscriber sub = n.subscribe("/darknet_ros_3d/bounding_boxes",50,chatterCallback); ros::spin(); return 0; } ，然后删除function output= myfunction(filename) delimiter = {';','='}; %% Read columns of data as text: formatSpec = '%s%s%s%s%s%s%[^\n\r]'; %% Open the text file. fileID = fopen(filename,'r'); dataArray = textscan(fileID,formatSpec,'Delimiter',delimiter,'TextType','string','ReturnOnError',false); %% Close the text file. fclose(fileID); 和filename行代码，但这是行不通的。

解决方法

在循环中使用此自动生成的功能循环遍历您拥有的文件（名称）

% path to folder with txt-files
pFlr = pwd; % path to working directory
Lst = dir( fullfile(pFldr,'*.txt') ); % only get txt-files

for i = 1:length(Lst)
   % path to file
   pFl = fullfile( Lst(i).folder,Lst(i).name );
   % read file by calling the auto-generated function
   Dat1 = myfunction( pFl );
end

通过这种方式，您可以循环访问所有文件，例如将数据存储在表中：

k = 1; % control variable
for i = 1:length(Lst)
   % path to file
   pFl = fullfile( Lst(i).folder,Lst(i).name );
   % read file by calling the auto-generated function
   Dat1 = myfunction( pFl );


   % do something with this data,e.g. store it
   if i == 1 % allocate data if
      Dat = Dat1;
      % extend for allocation
      vSz= height(Dat1)*length(Lst);
      Dat(vSz,:) = Dat1(1,:); % assign the first row of the first table to the last row of the allocated table to expand it
   else
      Dat(k:k+size(Dat1)-1,:) = Dat1;
   end
   k = k + size(Dat1);
end
% crop table
Dat = Dat(1:k-1,:);
