By default, the order is set to ascending order. In the above syntax, the direction will define the order in which we want to sort the rows, like ascend for ascending order of rows and descend for descending order of rows. output = sortrows(matrix, column, direction) The third syntax of sortrows() is given below. If we only pass a single column number with the same values present, the function will not change the position of the rows. If we look at the third and fourth columns of the New_matrix matrix, we can see that the elements of the third and fourth columns are sorted. If two or more of the same values are present in the current column, the function will move to the next column number present in the given vector.įor example, let’s sort the rows of a matrix using the second and third columns for sorting. We can also pass multiple column numbers in a vector, and the function will sort the rows according to the first column number. If we don’t pass the column number, the function will use the first column of the matrix for sorting rows. We can use the above syntax to set the column number from the input matrix, which will be used in sorting the rows present in the given matrix. The second syntax of the sortrows() function is given below: output = sortrows(matrix, column) We can pass a matrix of any size inside the sortrows() function. If we look at the first column of the My_matrix matrix, we can see that the second row will come first because the first element of the second row is the smallest, and the first row with the highest first value will come last in the output. We can compare the two matrices in the output to check the result.

We created a 3-by-6 matrix in the above code and sorted its rows. clcĬreate A Custom Sort Order For Your Excel PIVOT TABLE My_matrix = If two or more rows have the same first element, the function will compare their second elements, and so on.įor example, let’s sort the rows in a matrix using the above syntax. The above syntax will sort the rows in the given matrix according to the elements of the first column or the first element of each row in ascending order. The first syntax of the sortrows() function is given below: output = sortrows(matrix) We can use the sortrows() function of Matlab to sort rows present in a matrix. Use the sortrows() Function to Sort Matrix Rows in MATLAB
But if the table is sorted according to the first letter of patients’ names, we can see the person easily because now we only have to look at the names starting from a specific letter. In data analysis and processing, sorting is essential because it will make it easy to analyze and process data when it is sorted.įor example, if we have a table of patients in a hospital and we want to find a specific person, and if the table is not sorted, we will have to go through all the data to find a person. This tutorial will discuss sorting rows present in a matrix using the sortrows() function in MATLAB. Use the sortrows() Function to Sort Table Rows in MATLAB.Use the sortrows() Function to Sort Matrix Rows in MATLAB.
