How to remove the part where on the left column there is 1.0 but the values on the right one are different? Identifying the repeated rows in a matrix and comparing them to another matrix, How to create an array that counts the number of consecutive repeating numbers in a given array. Would the reflected sun's radiation melt ice in LEO? ( e 1 t You get [3,4,8,9,10] as you should. Seems [5,1] is the correct answer. r h i - MATLAB Answers - MATLAB Central Find in a cell array? r The FloydWarshall algorithm is a good choice for computing paths between all pairs of vertices in dense graphs, in which most or all pairs of vertices are connected by edges. s Not the answer you're looking for? 1 So what *is* the Latin word for chocolate? I'm not sure how to tackle this. They are in there in no 'specific' order, so a sample of the array would be [1,1,1,1,2,2,2,1,1,2,2,3,3]. 2 ) Removing duplicates preserving the order goes like this: which still preserves the last entry found. The length() function is used to return the length of the specified array.
