How to attribute numeric values to a function?

Hello everyone!

MatLab does not accept numeric attributes directly. So, how can it be done?

Thank you!

Your question is not clear

Answer 1

Why store the result in a different variable

V = input('Enter a number: ') ;
switch (V)
case 1
   out = sin(2) ;
case 2
   out = cos(1) ;
otherwise
   out = NaN ;
end

Alternatively you can store anonymous functions in a cell array, but if I were you I would avoid road that for now.

Try this, more GUI-based, nicer way of doing it:

buttonCaptions = {...
'function1=cos(1.0498*8000);',...
'function2=sin(0.6584*8000);',...
'function3=sin(0.6584*8000);',...
'function4=sin(0.6584*8000);',...
'function5=sin(0.6584*8000);',...
'function6=sin(0.6584*8000);',...
'function7=sin(0.6584*8000);',...
'function8=sin(0.6584*8000);',...
'function9=sin(0.6584*8000);'}
buttonNumber = menu('What function do you want to run?', buttonCaptions)
switch buttonNumber
  case 1
    result = cos(1.0498*8000);  
  case 2
    result = cos(1.6584*8000);
  case 3
    result = cos(1.0498*8000);  
  case 4
    result = tan(1.6584*8000);
  case 5
    result = acos(1.0498*8000);  
  case 6
    result = cosd(1.6584*8000);
  case 7
    result = asin(1.0498*8000);  
  case 8
    result = sind(1.6584*8000);
  case 9
    result = atan2d(1.0498*8000);  
end
message = sprintf('The result of the function is %f', result);
uiwait(helpdlg(message));

Obviously make changes as needed.
