duplicates

Using this method on a 8x8 matrix: >> [junk,index] = unique(data,'first'); %# Capture the index, ignore junk >> data(sort(index)) %# Index data with the sorted index Outputs the format in 64x1 format (if no repeats are found) or nx1 if some repeats are found. My question is how do I keep the matrix format without the sorting? i need it to check unique(rows) for duplicates not unique cells. And to delete the duplicate rows but keep the format (dont arrange/sort). If you want unique rows, while keeping original order, try this: [M,ind] = unique(data, 'rows', 'first'); [~,ind] = sort(ind); M = M

How to build a .bundle from source code? This might sound like a simple problem but it has been hurdling me for a week... Here is my problem: I have a bunch of .c and .h files that are organized in a folder and its sub folders. The source code was written and compiled with gcc make and tested by many other make tools. The source code has some utilities and command line tools and it has more code that serve as library for those utilities and tools. It is the files that serve as libraries that I want to reuse. (By library I don't mean static library or something, I just mean that some .c and .h

I have an object called FormObject that contains two ArrayLists - oldBooks and newBooks - both of which contain Book objects. oldBooks is allowed to contain duplicate Book objects newBooks is not allowed to contain duplicate Book objects within itself and cannot include any duplicates of Book objects in the oldBooks list. The definition of a duplicate Book is complex and I can't override the equals method as the definition is not universal across all uses of the Book object. I plan to have a method on the FormObject class called removeDuplicateNewBooks which will perform the above

I have two table to contain state (state_table) and city (city_table) of countries The city table is having state_id to relate it with state_table Both the tables are already having data in it. Now the problem City table contains multiple entries of a city within one state. And another cities may or may not have the same city name as well e.g.: cityone will have 5 occurrence in the city table with stateone and 2 occurrence with statetwo So how will I write a query to keep one city for each state and delete the rest? Schema follows CREATE TABLE IF NOT EXISTS `city_table` ( `id` int(11) NOT NULL

This question already has an answer here: Java Scanner class reading strings 5 answers I got the following code: int nnames; String names[]; System.out.print("How many names are you going to save: "); Scanner in = new Scanner(System.in); nnames = in.nextInt(); names = new String[nnames]; for (int i = 0; i < names.length; i++){ System.out.print("Type a name: "); names[i] = in.next(); } System.out.println(names[0]); When I run this code, the scanner will only pick up the first name and not the last name. And it will sometimes skip a line when trying to enter a name, it will show up as if I had
