![]() In the above code, we used the diag() function to find the diagonal entries from the given matrix, and you can see the function returned the diagonal entries of the given matrix. For example, let’s get the main diagonal entries from a given matrix. You can also use the diag() function to get the diagonal entries from a matrix. As you can see, the size of the diagonal is 6圆 now because the vector is placed above the main diagonal, and to ensure all the elements are placed inside the matrix, the size of the matrix increased. In the above code, we created a diagonal matrix with the elements placed above the main diagonal. For example, let’s place the vector above the main diagonal. ![]() If the second argument is less than 0, the vector will be placed below the main diagonal. If the second argument is greater than 0, the vector will be placed above the main diagonal. If the second argument is equal to 0, the vector will be placed on the main diagonal. You can also change the position of the diagonal by using a second argument inside the diag() function. ![]() If the number of elements is 5, then the diagonal matrix will be 5x5. The diag() function creates a square matrix depending on the number of elements present inside the given vector. In the above code, we made a 5x5 diagonal matrix with the diagonal entries stored in the variable vector. For example, let’s make a diagonal matrix from a given vector. To make a diagonal matrix or to get the diagonal entries of a matrix, you can use the diag() function in MATLAB. ![]() Make Diagonal Matrix Using diag() Function in MATLAB In this tutorial, we will discuss how to make a diagonal matrix using the diag() and spdiags() function in MATLAB. ![]()
