Praneeti - you may need to show your code and explain how you would like to change the if statement to an array.

if pos(1)<=  0.1589+0.06+0.1 && pos(1)>=0.1589+0.06 && pos(2)<=0.4120+0.12+.1 && pos(2)>=0.4120+0.12

    %             v1Fcn;
    %             fprintf(fid_click,'%.2f   %.2f    %d   %s    %s \n',264,451,1,datestr(now),'F101');
    te = toc(t_start_exp);
    fprintf(fid_click,'%d     %.6f  %.2f   %.2f    %d   %s %.2f\n',floor(te),(te-floor(te)),264,451,1,'F101',0000);
    
    tag_for_plot = 1;
    %flag_text = 1;
else

these are the cordinates and i want it to be arranged in an array format i.e. this if statement . How to do that?
