Read about diff. This will get the difference of successive rows. If decreasing diff would be negative, if increasing diff will be positive.

x=[100:-5:0] %an example
issorted(x,'strictdescend') %to check if they are sorted
abs(diff(x))==5

Try the function findchangepts(), in versions of MATLAB r2016a and later.
