how to use a parameter name list as input for a function?

조회 수: 19(최근 30일)
Dear All,
I have a tryparel function as below
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function out=tryparel(paramlist)
disp(a)
disp(b)
out=a+b;
%%%%%%%%%%%%%%%%%%%%%%%%%%%
To use this function above I would like to do below
paramlist=['a,' , 'b'];
out=tryparel(paramlist)
BUT I always get errors. Can anyone help me about this?
I have to write a script calling this type of function where the input variable list is really long.
Thanks

Skirt, you were very close. You just need to use a cell array:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function out=tryparel(paramlist)
disp(a)
disp(b)
out=a+b;
%%%%%%%%%%%%%%%%%%%%%%%%%%%
paramlist = {4 , 10};
out = tryparel(paramlist{:})
If you instead want to do something like this:
a = 4;
b = 10;
paramlist = {'a','b'};
... then don't do this. Instead use a structure such as:
P.a = 4;
P.b = 10;
paramNameList = {'a','b'};
paramList = cellfun(@(name)P.(name), paramNameList, 'Un',0)
out = tryparel(paramList{:})
Did this answer your question? If so, be sure to hit "accept".
