Thread Subject: Calling a function by looping through a vector

Hello everybody,
I'm trying to call a function that takes a vector and does performs an operation on it.
I have multiple vectors to send it so I though of sending the vectors in a loop:

a, b and c are all vectors.

x = ['a' 'b' 'c'];

for i = 1 : length(x)
    PerformOperation(x(i))
end

instead of:

PerformOperation(a)
PerformOperation(b)
PerformOperation(c)

Could somebody tell me how to call my function by looping through a vector? The second solution seems like a hack and I'm trying to learn the best possible way to do this.

Much appreciated.

x = {a b c};
for i = 1: length(x)
   yourfunc(x{i});
end
