Hi all!!

when I use a variable with this {:}, what does it mean?

When used alone, it means to display all contents of a cell array.

C = {magic(3);'how';rand(1,2);'pizzaz';magic(8)};
C{:}

When passed to a function, it will form a comma-separated list. For example:

C = {magic(3);magic(2)}
isequal(C{:})  % This is the same as isequal(C{1},C{2})

Now change it to:

C = {magic(3);magic(3)}
isequal(C{:})  % This is the same as isequal(C{1},C{2})
