Same as built-in unique, but works for cell arrays where each element is a numeric array. For A a cell array of matrices (or vectors), returns Au, which contains the unique matrices in A, idx, which contains the indices of the last appearance of each such unique matrix, and idx2, ...
We are required to write a function that returns the index of the very first element that appears at least twice in the array. If no element appears more than once, we have to return -1. We have to do this in constant space (i.e., without utilizing extra memory)....
● 如果你有一个vector、string、deque或数组,你需要鉴别出第n个元素或你需要鉴别出最前的n个元素,而不用知道它们的顺序,nth_element是你应该注意和调用的。 ● 如果你需要把标准序列容器的元素或数组分隔为满足和不满足某个标准,你大概就要找partition或stable_partition。 ● 如果你的数据是在list中,你可以直接...
Let's call a subarray unique if there is an integer that occurs exactly once in the subarray.You can perform the following operation any number of times (possibly zero): choose an element of the array and replace it with any integer....

type with each element given a label, with the effect that we end up with a 1-D array of structured types that can be treated in the same way as any other 1-D array. The result is that the flattened subarrays are sorted in lexicographic order starting with the first element. ...
你须要鉴别出第n个元素或你须要鉴别出最前的n个元素,而不用知道它们的顺序,nth_element是你应该注意和调用的。● 假设你须要把标准序列容器的元素或数组分隔为满足和不满足某个标准,你大概就要找partition或stable_partition。 ● 假设你的数据是在list中,你能够直接使用partition和stable_partition,你能够使用list的...

We may want to get a set of unique values from an array. For this we have to use function array_unique(). This will take an array as input and return an array with unique elements of the old array. Here is our old array with some duplicate elements. ...
