Details:

signal v1.4.1
OS: Ubuntu Linux 20.04.2 LTS 64 bit

x = [0, 1.2, 3, -8, 0];
clustersegment(x)
error: clustersegment: =: nonconformant arguments (op1 is 2x1, op2 is 1x3)
error: called from
    clustersegment at line 56 column 30

The error disappears when x is a column matrix instead of a row matrix, but
the function then produces the wrong results

>> clustersegment(x')
ans =
{
  [1,1] = [](0x0)
  [1,2] = [](0x0)
  [1,3] = [](0x0)
  [1,4] = [](0x0)
  [1,5] = [](0x0)
}

Correct result should be
ans =

   2
   4
