x=input('Enter the marks');
switch (x)
    case {x>=90 && x<=100}
      disp('O');
    case {x>=80 && x<=89}
      disp('A+')

Aditi.. Error is very simple

Basically && Operator in matlab perform Logical Operation.

You simply have to replace the && with &.

if true
 x=input('Enter the marks');
switch (x)
  case {x>=90 & x<=100}
    disp('O');
  case {x>=80 & x<=89}
    disp('A+')
 case {x>=70 & x<=79}
    disp('A');
  case  {x>=60 & x<=69}
    disp('B+');
 case  {x>=50 & x<=59}
    disp('B');
    case  {x>=40 & x<=49}
    disp('c');
case  {x<40}
    disp('F');
  otherwise
      disp('No grade')
end
end
