How to check whether point is changed or not in MatLab? - ischange -- MatLab How to check whether point is changed or not in MatLab? [Ans] ischange NOT ischanged [Syntax] < TF> = ischange(<A>) < TF> = ischange(A,<method>) < TF> = ischange( ___ ,<dim>) < TF> = ischange( ___ ,<Name>,<Value>) [<TF>,<S1>] = ischange( ___ ) [TF,S1,S2] = ischange( ___ ) [Description] Find abrupt points in data. i.e. find the points which is changed by your definition or by default. By default, <method> is set to mean. e.g. TF = ischange(A) It will return true when there is an abrupt change in mean of corresponding element of A. Otherwise, return false. TF = ischange(A,'variance') It will return true when there is an abrupt change in variance of corresponding element of A. Otherwise, return false. (1) [<TF>,<S1>,<S2>]=ischange(__) It will return 3 variable. <TF> check an abrupte...
