difference between abrupt changes functions

Hey,
I'm was trying to find changes in my signal and I used 'findchangepts' function which worked really good (I used both mean and linear statistics) but it works only with signal processing toolbox which is missing to my colleagues.
Now I found the function 'ischange' which looks similar and doesn't need the toolbox but it brings different results.
Do anyone know what is the difference between these two functions?
Thanks!

Can you please attac your attempts and data?
I'm attaching two figures of the same signal. One with findchangepts division and the other with ischange. Both of the cange points are different between the two figures.
To examine a fig file, you have to open it in Matlab at first. Please post some data and the used code instead. Maybe a screenshot is easier also for a comparison of the results you get.
