switch/case statement matlab code

function myFunc = executeCmdByKind(var1,kind)

switch kind
case 'open'
cmdToExecute = [''var1 '','' locationIs '',''clear''];

case 'close'
cmdToExecute = [''var1 '','' locationIs '',''delete''];

case 'move'
cmdToExecute = [''var1 '','' locationIs '',''move''];



   end
a = system(cmdToExecute);
end

My question is : is there a better way "optimal" to write this code as I call the same cmdToExecute only the latest arg changes

Thanks,

There are, as always, several ways of doing it. I'd do it like the following:

function myFunc = executeCmdByKind(var1,kind)
  a = {'open', 'close', 'move'};
  b = {'clear', 'delete', 'move'};
  logi = ismember(a, kind);
  cmdToExecute = [var1, locationIs, b{logi}];

That's not the nicest code, but it's short, if you want that ;-) First I look via kind which index it has in the vector a and after retreiving the index, I can then select the corresponding element from b :-)

Edit: Short and it's easily expandable in the future with more elements :-)

Your syntax makes no sense to me, but I'll stick with it. You could streamline your code like this I guess:

function myFunc = executeCmdByKind(var1,kind)

switch kind
case 'open'
    last = ''clear'';

case 'close'
    last = ''delete'';

case 'move'
    last = ''move'';

end

cmdToExecute = [''var1 '','' locationIs '', last];
