 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...

 How to check the point in the plot is outlier in MatLab? - MatLab How to check the point in the plot is outlier in MatLab? [Ans] isoutlier [Syntax] TF = isoutlier(A) TF = isoutlier(A,method) TF = isoutlier(A,'percentiles',threshold) TF = isoutlier(A,movmethod,window) TF = isoutlier( ___ ,dim) TF = isoutlier( ___ ,Name,Value) [TF,L,U,C] = isoutlier( ___ ) [Description] find outliers in data. outliers, outlier points, are  abnormal points. In MatLab, by default, an outlier is a value that is more than 3 scaled MAD(median  absolute derivations) away from the median. isoutlier(<A>)  If A is a vector, it will calculate median of A and check each point in the vector is an outlier or not. If A is a matrix or table, it will operate column by column of A. i.e. it will operate every columns  of A.  If A is a multi-dimension array, it will operate along the first dimension whose size is not equal to 1. isoutlier(<A>, <methodName>) It will call isout...

 How to add legend in Matlab? - legend -- MatLab  How to add legend in Matlab? [Ans] legend [Description] Add a legend to axes of the figure. more details on: Add legend to axes - MATLAB legend (mathworks.com)

How to check the ax is hold or not in MatLab? - ishold -- MatLab ishold command [Description] tf =ishold return true when current ax is hold. Otherwise, return false. tf=ishold(ax) return true when the ax is hold. Otherwise, return false. [NOTE] Great Importance !!! Pay  a lot of attention on it!!! When you use ishold command but there are no figure . The MatLab will create a new empty figure and return false. e.g. more details on: Current hold state - MATLAB ishold (mathworks.com)

 How to hold plots in MatLab? - hold -- MatLab hold command [description] the hold command is used to set to hold  state of plots or not. When the plot is hold, it will not disapear the next time you plot the other graph. You will see two graphs will be overlapping. hold on  or  hold ('on') hold the state on hold on the current plot. it will not disapear the next time you plot the other graph. hold off or hold ('off'') hold the state off e.g. above fig. are about no 'hold on' above fig. are about 'hold on' hold  toggle hold state between on and off. hold (ax, ___) set ax hold state. more details on Retain current plot when adding new plots - MATLAB hold (mathworks.com)
