This MATLAB function returns a square diagonal matrix with vector v as the main diagonal.

This MATLAB function returns the block diagonal matrix created by aligning the input matrices A1,...,AN along the diagonal of B.

The Create Diagonal Matrix block populates the diagonal of the M-by-M matrix output with the elements contained in the length-M vector input D.

This MATLAB function returns a square diagonal matrix with the elements of vector v on the main diagonal.

Balancing is an attempt to concentrate any ill conditioning of the eigenvector matrix into a diagonal scaling. Balancing usually cannot turn a nonsymmetric matrix into a symmetric …

Diagonal Matrix A matrix is diagonal if all elements above and below the main diagonal are zero. Any number of the elements on the main diagonal can also be zero. For example, this 4-by-4 …

The matrix representation of the second difference operator is a good example of a sparse matrix. It is a tridiagonal matrix with -2s on the diagonal and 1s on the super- and subdiagonal. There …

Block Diagonal Matrix Create a block diagonal matrix. Create a 4-by-4 identity matrix and a 2-by-2 matrix that you want to be repeated along the diagonal.

This MATLAB function extracts the nonzero diagonals from m-by-n matrix A and returns them as the columns in min(m,n)-by-p matrix Bout, where p is the number of nonzero diagonals.

The upper triangular portion of a matrix includes the main diagonal and all elements above it. The shaded elements in this graphic depict the upper triangular portion of a 6-by-6 matrix.
