How to show the values are constant inside a cell array

Hi,
I have a cell array that is 4x6. Inside each cell I have 1x31 values.
I am studying the change of my variables in time. Thus, for a t_length=31 (31 values in each cell), I would like to show whether in each cell the values are or not constant.
Could you please help me with it?

Presuming interpreted the meaning of "constant" in each cell,
>> c{:} % small demo cell array first,last constant, other two alike
ans =
3 3 3 3
ans =
1 2 3 4
ans =
1 2 3 4
ans =
3.1416 3.1416 3.1416 3.1416
>> cellfun(@(x) all(x==x(1)),c)
ans =
2×2 logical array
1 0
0 1
>>
returns locations in the cell array that all are constant (every value in the vector in the cell are the same).
If the Q? is which cells are equal to each other, that's a "compare one to every other" combinational thing.

You're talking about subsections within these vectors that are constant? Is that anywhere within them that diff() two or more points is zero or what other definition is "constant"? What about
v=[0 1 2 2 1 1 2 2 3 4 ...
? What is desired output or what are constraints on inputs?
