I have a txt file and from that i am creating several column vectors and I want to extract range few values out of these column vectors so I am using a for loop and if condition to check the each element in that coumn. After that I am selecting range of rows and creating a new column vector out of it. Now I want to perform some operations on this newly created column vector but the promblem i am facing is how to call the names of these colomun vectors as it contains varibale. below you can find the script i used to create new column vectors

for a=1:count_rows
    if Command(a,1)=="-1" && Command(a+1,1)=="0"
         c=a;
        
    end
 
    
    if Command(a,1)=="0" && Command(a+1,1)=="-1"
       
        
        d=a;
       
        relaxs=['relaxs',num2str(count1)];
        relaxv=['relaxv',num2str(count1)];
        relaxtime=['relaxtime',num2str(count1)];
        relaxcommand=['relaxcommand',num2str(count1)];
        assignin('caller',relaxs,S(c:d,1));
        assignin('caller',relaxv,V(c:d,1));
        assignin('caller',relaxtime,Time(c:d,1));
        assignin('caller',relaxcommand,Command(c:d,1));
        count1=1+count1;
    end
