Priyanka - if you just want to write the structure to file, then just try using fopen to open the file, fprintf to write the data (each of the four variables) to file, and fclose to close the file.

在 MATLAB Online 中打开

s1.name = 'fred';
s1.age = 42;
s1.height = 170;
s1(2).name = 'alice';
s1(2).age = 29;
s1(2).height = 160;
fileID = fopen('use of structure .txt','a');
    fprintf(fileID, 'Missile #         :%s \n', s1.name);
    fprintf(fileID, 'Operator Name     :%s \n', s1.age);
    fprintf(fileID, 'Operator Name     :%s \n', s1.height);
    fprintf(fileID, 'Missile Type      :%s \n', s1(2).name);
    fprintf(fileID, 'Missile ID        :%s \n',s1(2).age);
    fprintf(fileID, 'Container Number  :%s \n', s1(2).height);
 
 fclose(fileID);

simply fprintf is not write structure variable in text file

Error occur ''Scalar structure required for this assignment.

Error in Untitled (line 36)

s1.name = 'fred';''
