Hello Matlab folks,

I am trying to retrieve a cell and change some of its values with only one command line.

I have today :

>> x = {'a';'b';'c';'d';'e'};
>> x{2} = 'y';x{4} = 'z';

I am looking for something like:

>> UnknownFunction({'a';'b';'c';'d';'e'},2,'x',4,'z');

And because it is not funny otherwise, I can't create an UnknownFunction.m myself as I need to use only native Matlab function.

Any Idea ?

Thanks

Thanks dpb , I thought so too until the OP commented xd:

subsref({'a';'b';'c';'d';'e'},substruct('{}',{2}))
% or you can use the below ones if the user made anonymous function is allowed
retriever = @(x,y) x(y); 
%                   ^_^  - use {} if you want
retriever({'a';'b';'c';'d';'e'},2)

I actually just found the function that suits my need.

getcolumn({'a';'b';'c';'d';'e'}',[2 4])

Thanks.
