MATLAB: How can you fix this question

switch

Switch Today
  case 'Friday'
   disp ('Happy Friday')
  case ['Saturday','Sunday']
   disp ('YAY Weekend')
  else
   disp ('No Weekend')
end

Best Answer

There are several small mistakes, all of which a careful reading of

doc switch

could have solved.

MATLAB is case-sensitive, so you need to write "switch" not "Switch"
You need to enclose multiple cases in curly brackets, not square brackets
You need to use "otherwise", not "else", in a switch statement

switch Today
  case 'Friday'
   disp ('Happy Friday')
  case {'Saturday','Sunday'}
   disp ('YAY Weekend')
  otherwise
   disp ('No Weekend')
end

MATLAB: Matrix dimensions must agree error in if loop

day = input('What day is today? -> ', 's');
lo = any(strcmpi(day,{'saturday','sunday'}));
if lo
    disp(['Its ' day ' ! Its weekend!'])
else 
    disp(['Its ' day ' ! Get to work!'])
end

Illustration to the error you received:

day = input('What day is today? -> ', 's');
What day is today? -> Sunday
>> day == 'Saturday' | day == 'Sunday'
Matrix dimensions must agree. 
>> day == 'Saturday'
Matrix dimensions must agree. 
>> day == 'Sunday'
