Getting a tuple of DataArrayInt

+ +In this simple example we create an array of integers arranged into 3 +tuples per 2 components, and finally print the second tuple. +\snippet MEDCouplingExamplesTest.py Snippet_DataArrayInt_getTuple_1 +The output is +
 [9, 10]
+Note that we can traverse all tuples in the array by simply iterating +over it as the code below does. +\snippet MEDCouplingExamplesTest.py Snippet_DataArrayInt_getTuple_2 +Its output follows. +
+(7, 8)
+(9, 10)
+(11, 12)

Building a permutation array

+ +Here we create two arrays containing same values but in different order and then we use +\ref ParaMEDMEM::DataArrayInt::buildPermutationArr "DataArrayInt::buildPermutationArr()" to get +an array showing in what places the values of \b b array are located in \b a array. +\snippet MEDCouplingExamplesTest.cxx CppSnippet_DataArrayInt_buildPermutationArr_1 +The result array \b c contains [1,0,4,2,3]. + +

Inverting renumbering maps

Finding values in range in DataArrayDouble

+ +In this example we create an array \b da containing same values as ones returned by +\c range( \c 10 ). Then we get an array of indices of values of \b da being in +range [ 2.5, 6 ]. +\snippet MEDCouplingExamplesTest.cxx CppSnippet_DataArrayDouble_getIdsInRange_1 +As result contents of the array \b da2 are as follows. +
