 mkdir(database) % will make new folder
x= strcat(database,'/Subtrain'); %horizontally concatenatesstrings in arrays
save(x,'Subtrain') % saves variable 
y = strcat(database,'/trainID');
save(y,'trainID')

am i right or not ?? and what is "/trainID" here,and how this save will work ?

在 MATLAB Online 中打开

Your code opens a folder given in database and in that folder saves two .mat files with name Subtrain.mat and trainID.mat. In these files, the data is provided by variables Subtrain and trainID respectively.

clc; clear all ;
database = 'Folder' ;
Subtrain = rand(100,1) ; 
trainID = 'This can be number or string' ;
mkdir(database) % will make new folder
x= strcat(database,'/Subtrain'); %horizontally concatenatesstrings in arrays
save(x,'Subtrain') % saves variable 
y = strcat(database,'/trainID');
save(y,'trainID')
