How do you find the largest element in an array in MATLAB?

M = max( A ) returns the maximum elements of an array.

Table of Contents

If A is a vector, then max(A) returns the maximum of A .
If A is a matrix, then max(A) is a row vector containing the maximum value of each column of A .

How do you find the largest index in MATLAB?

You can use max() to get the max value. The max function can also return the index of the maximum value in the vector. To get this, assign the result of the call to max to a two element vector instead of just a single variable. Here, 7 is the largest number at the 4th position(index).

How do you find the second largest in MATLAB?

Direct link to this answer

[ii,ii] = sort(A); out = A(ii([2,end-1]));
out = A([2,end-1]);
A1 = unique(A); out = A1([2,end-1]);

How do you find the index of an element in MATLAB?

In MATLAB the array indexing starts from 1. To find the index of the element in the array, you can use the find() function. Using the find() function you can find the indices and the element from the array. The find() function returns a vector containing the data.

How do you find the second largest element in an array?

Find 2nd Largest Number in Array using Arrays

import java.util.Arrays;
public class SecondLargestInArrayExample1{
public static int getSecondLargest(int[] a, int total){
Arrays.sort(a);
return a[total-2];
}
public static void main(String args[]){
int a[]={1,2,5,6,3,2};

How do you find the greatest number in an array?

To find the largest element from the array, a simple way is to arrange the elements in ascending order. After sorting, the first element will represent the smallest element, the next element will be the second smallest, and going on, the last element will be the largest element of the array.

How do you find the extrema of a function in MATLAB?

To add the Find Local Extrema task to a live script in the MATLAB Live Editor:

On the Live Editor tab, click Task and select the Find Local Extrema icon .
In a code block in the live script, type a relevant keyword, such as extrema or find . Select Find Local Extrema from the suggested command completions.

How do you find the greatest element in an array?

How do you find the third largest element in an array?

Java program to find the 3rd largest number in an array

Compare the first two elements of the array.
If the first element is greater than the second swap them.
Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.
Repeat this till the end of the array.

How do you print the largest element in an array?

Algorithm

STEP 1: START.
STEP 2: INITIALIZE arr[] = {25, 11, 7, 75, 56}
STEP 3: max = arr[0]
STEP 4: REPEAT STEP 5 for(i=0; i< arr.length; i++)
STEP 5: if(arr[i]>max) max=arr[i]
STEP 6: PRINT “Largest element in given array:”
STEP 7: PRINT max.
STEP 8: END.
