string inputs and if else statement

function untitled(country1,state1,country2,state2,names,days,avg_days,dailycases)
if state1= isempty and state2 = isempyty
Index1 = strcmpi(names,country1);
 dailydata1= dailycases(Index1,:);
 daily_cases1 = movmean(dailydata1, avg_days);
 daily__cases1=daily_cases1(1,:)
 figure
 subplot(2,1,1)
 title('country1')
 bar(days(1:end-1),daily__cases1);
Index2 = strcmpi(names,country2);
 dailydata2= dailycases(Index2,:);
 daily_cases2 = movmean(dailydata2, avg_days);
 daily__cases2=daily_cases2(1,:)
 subplot(2,1,2)
 title('country2')
 bar(days(1:end-1),daily__cases2);
else
  Index1 = strcmpi(names,state1);
 dailydata1= dailycases(Index1,:);
 daily_cases1 = movmean(dailydata1, avg_days);
 daily__cases1=daily_cases1(1,:)
 figure

end

how i should write code after if statement so that if state =empty

the it execute the if part and else it execute else part

note that country1, country2,state1,state2 they all are string input

‘... how i should write code after if statement so that if state =empty ...’

This line:

if state1= isempty and state2 = isempyty

becomes:

if isempty(state1) && isempty(state2)

If that is not true (both are not empty), the else section should execute.
