How to write a function to delete the duplicated arrays?

Hi, I have tried to write a function that finding to duplicated numbers and remove them in my array. I know the unique function is useful for such kind of problems but it is not for me. For instance,my array is [1 2 2 2 3 1]. I want to delete the consecutive numbers such [1 2 3 1]. Please help me about this.

Answer 1

[Jos (10584)]

A = [1 2 2 2 3 1 1]
tf = [true diff(A)~=0]
B = A(tf)

I want to find solution as [1 2 3 1]. it is not useful.

And Jos' solution does reply [1,2,3,1]. Therefore I'm convinced, that it is useful. +1

See http://www.mathworks.com/matlabcentral/fileexchange/41813-runlength:

A = [1 2 2 2 3 1 1];
B = RunLength(A);
