Jan 11, · 1) Initialize both first and second smallest as INT_MAX first = second = INT_MAX 2) Loop through all the elements. a) If the current element is smaller than first, then update first and second. b) Else if the current element is smaller than second then update second/5. Aug 07, · This is probably very simple. I have an array of size, say 10 by In each column, there is definitely an element with a value of 0, the rest of the nine: values > 0. Now, I want a row vector containing the second smallest values from each column of the original array. I'm trying to find the second smallest element in an array of n elements using only n + ceil(lg n) - 2 comparisons. The hint in CLRS says to find the smallest element. This takes n - 1 comparisons so I'm left with ceil(lg n) - 1 comparisons to find the second smallest, once I know the largest.. Any ideas?

# Find second smallest element in array matlab

If you are looking C implementation to to find second smallest element in a one dimensional array]: Find minimum (Smallest) element in Array

Documentation Help Center. If A is a vector, then min A returns the minimum of A. If A is a matrix, then min A is a row vector containing the minimum value of each column. If A is a multidimensional array, then min A operates along the first array dimension whose size does not equal 1 dutty dancing hypa 4000 firefox, treating the elements as vectors. The size of this dimension becomes 1 while the sizes of all other dimensions remain the same. If A is an empty array with first dimension 0then min A returns an empty array with the same size as A. For example, if A is a matrix, then min A,[],2 is a column vector containing the minimum value of each row. For example, min A,[],'includenan' includes all NaN values in A while min A,[],'omitnan' ignores them.

May 03, · I want to find the 2nd minimum value in an array. min(A) can be used to find the minimum value, but I want to find the the number greater than minimum (2nd minimum). Aug 29, · Finding second smallest element in a row.. Learn more about second smallest, non zero element, find, column, matlab. I have an array, I need to be able to select 2, or 4 or so on 'n' minimum (smallest) values from the specific array? I know i can use 'min' function but this only gives one smallest value. If dim = 1, then min(A,[],1) returns a row vector containing the smallest element in each column. If dim = 2, then min(A,[],2) returns a column vector containing the smallest element in each row. min returns A if dim is greater than ndims(A). Aug 07, · This is probably very simple. I have an array of size, say 10 by In each column, there is definitely an element with a value of 0, the rest of the nine: values > 0. Now, I want a row vector containing the second smallest values from each column of the original array. I know this is an extremely late reply but I am hoping to help anyone who may have this question later. If A is the array of elements, yu could try using the find function to determine the index of the n smallest elements. Jun 07, · How to find second largest value in an array?. Learn more about array. Toggle Main Navigation Be careful for the case where A only has one element. And cases where A has duplicate elements. finds the maximum of the above, which corresponds to the second maximum. Look up logical indexing in matlab for more details. Quite a clever. In this case, the logical array being used as an index is the same size as the other array, but this is not a requirement. For more information, see Array Indexing. Some problems require information about the locations of the array elements that meet a condition rather than their actual values. Write an efficient C program to find smallest and second smallest element in an array. A Simple Solution is to sort the array in increasing order. The first two elements in sorted array would be two smallest elements. Time complexity of this solution is O(n Log n). A Better Solution is to scan the. How can I find the indices of the 2 smallest elements in a vector without sorting? you'll get the second smallest element. I haven't benchmarked, but I would think this is faster than Phil's answer, at least for (very) large matrices. Matlab's sort is quicksort with big-o (n log(n)) whereas find .Finding second smallest element in a row.. Learn more about second smallest, non zero element, find, column, matlab. This is probably very simple. I have an array of size, say 10 by In each column , there is definitely an element with a value of 0, the rest of the. "second minimum value should occur": what does that mean? Unique function returns the vector in ascending order discarding any repetitive values. And the find function returns the index value. I want to find the 2nd minimum value in an array. min(A) can be used to find the minimum value, but I want to find the the number greater than minimum (2nd. I know i can use 'min' function but this only gives one smallest value. I do not want to sort the array in order and pick values. is there another way? . in the sense, you are looking for the smallest, the second smallest etc. Learn more about array. I want to find the second largest and minimum value in array? A=[1;10 .. for k=1:s %s is the number highest number will be shown. This MATLAB function returns the k smallest elements of A. If X is not unique, find(X==max(X)) can find more than one element. this is times faster than the SORT-method under Matlab a, Win7/ . max in the matrix by a very small number (probably less than the minimum). - Use find second smallest element in array matlab and enjoy Finding the second smallest value in each column of an array? - MATLAB Answers - MATLAB Central
