matlab - How to make a fusion of three similar looking graphs into one graph -

-

i have x-cordinate graphs plotted against time of particular data. more accuracy data taken 3 times n hence have set of 3 graphs. graphs obtained similar not accuracy of 90%..and there no method of each time taking data more accuracy. need set single standard graph incorporates features of 3 (sample graphs obtained) more accuracy. please suggest me method so.

an example of using mean/median:

%# data , noisy estimates t = 1:100; x = cumsum(rand(size(t))-0.5); x1 = x + randn(size(x))*0.7; x2 = x + randn(size(x))*0.9; x3 = x + randn(size(x))*1.2;  %# plot estimates clf subplot(211) plot(t,x1, t,x2, t,x3) legend({'estimate 1','estimate 2','estimate 3'})  %# mean/median across estimates subplot(212) plot(t,mean([x1;x2;x3]), t,median([x1;x2;x3])) hold on, plot(t,x, 'm:', 'linewidth',2), hold off legend({'mean','median','actual'})

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
