   for p=1:10
    s1{p}={'courses','days×','class','pro';
           'physic1',randperm(20,2),randperm(5,2),'poury';
           'math1',randperm(20,2),randperm(5,2),'saadat';
           'compbs',randperm(20,2),randperm(5,2),'azyzy';
           'physic1Lab',randperm(20,2),randperm(5,2),'mahlooji';
           'compLab',randperm(20,2),randperm(5,2),'alavy';
           'English',randperm(20,2),randperm(5,2),'tabary'}
   end

no it dosnt work! its result is: s1 =

    {7x4 cell}    {7x4 cell  }    'class'         'pro'     
    {7x4 cell}    {7x4 cell  }    [1x2 double]    'poury'   
    {7x4 cell}    [1x2 double]    [1x2 double]    'saadat'  
    {7x4 cell}    [1x2 double]    [1x2 double]    'azyzy'   
    {7x4 cell}    [1x2 double]    [1x2 double]    'mahlooji'
    {7x4 cell}    [1x2 double]    [1x2 double]    'alavy'   
    {7x4 cell}    [1x2 double]    [1x2 double]    'tabary'
