Trace for the above matrix is 5 + 4 + 7 = 16. For example, consider the following matrix. It is useful to prove results in linear algebra. Note that the matrix must be a square matrix (the number of rows and columns must be the same). The trace of a matrix is the sum of all the elements present in the principal diagonal (upper left to lower right). Now, calculate the square root of the sum of squares. For example, consider the following matrix.įirst, we will calculate the sum of the square of each element.ĩ 2 + 8 2 + 2 2 + 1 2 + 4 2 + 7 2 + 3 2 + 5 2 + 6 2Ĩ1 + 64 + 4 + 1 + 16 + 49 + 9 + 25 + 36 = 285 The normal of a matrix is the square root of the sum of squares of all the elements of a matrix. Before moving to, the program, first we will understand the what is normal and trace of a matrix. In this section, we will learn how to calculate the normal and trace of a matrix in Java.
