Swapping Two Elements in Each Row of a Matrix Without Loop in MATLAB Last Updated : 15 Mar, 2022 Comments Improve Suggest changes Like Article Like Report A Matrix is a two-layered cluster of numbers. In MATLAB, we can create a Matrix by entering components in each line as comma or space-delimited numbers and also, utilizing semicolons to stamp the finish of each line. Approach:Step 1: Pick 2 elements in a row using logical()Step 2: Get all possible Combinations using perms()Step 3: Pick 5 Random Numbers from 1 to 24 using Randi() functionStep 4: Logical Index to Pick Numbers in Each RowStep 5: Create A Matrix (Original)Step 6: Transpose the MatrixStep 7: Pick the Data. Each column contains two numbers from each row in the matrix AStep 8: Swap the valuesStep 9: Fill Back the DataStep 10: Transpose to give the Final ResultExample: Matlab % MATLAB Program to Swap 2 Elements % in each row without Loops % Step1 : Pick 2 elements in a row flag=logical([0 0 1 1]); % Step2 : Get all possible Combinations p=perms(flag); % Step3 : Pick 5 Random Numbers from 1 to 24 index1=randi(24,5,1); % Step4 : Logical Index to Pick Numbers in Each Row index=p(index1,:); % Step5 : Create A Matrix (Original) A=reshape(1:20,5,4) % Step6 : Transpose the Matrix B=A'; data=B(index'); % Step7 : Pick the Data % Each column contains two numbers from each row in the matrix A data=reshape(data,2,[]) % Step8 : Swap the values data=data([2,1],:) % Step9 : Fill Back the Data B(index')=data; % Step10 : Transpose to give the Final Result B=B' Output: Comment More infoAdvertise with us Next Article Swapping Two Elements in Each Row of a Matrix Without Loop in MATLAB A Akash7 Follow Improve Article Tags : Software Engineering Geeks-Premier-League-2022 MATLAB Matrix-Programs Similar Reads How to swap elements in the matrix in MATLAB? In this article, we will see the swapping of elements into a matrix in MATLAB. Different methods are illustrated below: Method 1: By changing elements of rows and columns  In this method, we are simply changing the elements of particular rows and columns in the specified rows and columns respectivel 3 min read How to Iterate through each element in N-Dimensional matrix in MATLAB? In MATLAB, a matrix is considered a two-dimensional array of numbers. Other programming languages work with numbers but in MATLAB, every number is a matrix or array. To create a matrix in MATLAB, numbers are entered in each row by adding a comma or space and the ending of each row is marked by a sem 4 min read How to Permute the Rows and Columns in a Matrix on MATLAB? In this article, we will discuss how to find the permutation of the rows and columns in a Matrix with the help of multiple approaches Method 1In this approach, we are simply permuting the rows and columns of the matrix in the specified format of rows and columns respectively.  For column permutation 4 min read Turn a Matrix into a Row Vector in MATLAB Conversion of a Matrix into a Row Vector. This conversion can be done using reshape() function along with the Transpose operation. This reshape() function is used to reshape the specified matrix using the given size vector. Syntax:reshape(A, sz) Parameters: This function accepts two parameters, whic 1 min read How to Create a Matrix From a Nested Loop in MATLAB? Matrices are 2-dimensional arrays that store numeric or symbolic data. It is convenient to create them with the help of nested loops as the outer loop creates the elements along one dimension and the inner loop creates the elements along the second dimension. In this article, we will see how to crea 2 min read Program to Interchange or Swap Columns in a Matrix Given a matrix having m rows and n columns, the task is to write a program to interchange any two Columns(i.e. column no. N and M given in the input) in the given matrix. Example: Input : N = 1, M = 2, mat[][] = {{2, 1, 4}, {1, 2, 3}, {3, 6, 2}}Output: mat[][] = {{1, 2, 4}, {2, 1, 3}, {6, 3, 2}} Inp 6 min read How to Randomly Shuffle Columns in MATLAB in Matrix? In this article, we are going to discuss the "random shuffling of columns in a Matrix " with the help of size() and randperm() function. The size() function is used to return the size of each dimension of the specified array "X" or the size of the specified matrix "X". Using Size() and randperm() 1 3 min read How to Select Random Rows from a Matrix in MATLAB? A matrix is an n x n array that stores integers, floating point numbers or alphanumeric data in MATLAB. Indexing a matrix is the same as indexing an array.  Syntax:matrix_name(i,j)where, i is the row number, and  J is the column number which is to be indexed.
