Complete the function transpose() which takes matrix[][] and N as input parameter and finds the transpose of the input matrix. A matrix with 9 elements is shown below. This article is attributed to GeeksforGeeks.org . For the transposed matrix, we change the order of transposed to 3x2, i.e. 1) Transpose matrix will formed by inter changing the rows and columns of the original matrix . Converting rows of a matrix into columns and columns of a matrix into row is called transpose of a matrix. (k, i)th element of (AB)t = (i, k)th element of AB. Transpose Of A Matrix Java Program - Example java program to read matrix size, elements and finds the transpose of a matrix. Each element of matrix [M] can be referred to by its row and column number. Transpose of a matrix is obtained by changing rows to columns and columns to rows. In other words, transpose of A[][] is obtained by changing A[i][j] to A[j][i].
