Find abrupt changes in data

`TF = ischange(A)`

`TF = ischange(A,method)`

`TF = ischange(___,dim)`

`TF = ischange(___,Name,Value)`

`[TF,S1] = ischange(___)`

`[TF,S1,S2] = ischange(___)`

specifies additional parameters for finding change points using one or more
name-value pair arguments. For example,
`TF`

= ischange(___,`Name,Value`

)`ischange(A,'MaxNumChanges',m)`

detects no more than
`m`

change points.
