D = diag(v) returns a square diagonal matrix with the elements of vector v on the main diagonal. D = diag(v,k) places the elements of vector v on the k th diagonal. k=0 represents the main diagonal, k>0 is above the main diagonal, and k<0 is below the main diagonal. Create a 1-by-5 vector.

Apr 19, 2021 · Make Diagonal Matrix Using spdiags() Function in MATLAB. To make a diagonal matrix with more than one diagonal or to get all the diagonal entries of a matrix, you can use the spdiags() function in MATLAB.

Basically I just need to know the values of D and U required in the expression to make A a diagonal matrix (where D is diagonal) as I can then use it to do an explicit calculation for a matrix exponential.

Mar 9, 2011 · The following gives the diagonal matrix D whose diagonal is the vector vec. It is written in a vectorized fashion in MATLAB. D = zeros(numel(vec)); [I,J] = ind2sub(size(D),1:numel(D)); ind = [I(:) J(:)]; ind = find(ind(:,1)==ind(:,2)); D(ind) = vec;

Feb 15, 2023 · The syntax for creating a diagonal matrix in MATLAB is diag(vector), such as diag([4, 5, 6]). You can also input a matrix instead of a singleton vector if you want to define the off-diagonal elements.

The diag () function in Matlab offers a straightforward way to create a diagonal matrix. The first parameter, v, is an array or vector containing the values to place along the matrix's diagonal. The second parameter, k, is an integer that indicates the diagonal’s position relative to the main diagonal. By default, k = 0 targets the main diagonal.

Nov 15, 2016 · You can flatten out your input matrix into a column vector using (:) indexing and then pass it to diag to place these elements along the diagonal of a new matrix. result = diag(X(:)) This will order the elements along the diagonal in column-major order (the default for MATLAB).

MATLAB provides a simple and efficient way to create diagonal matrices using the `diag` function. This function can generate a diagonal matrix from a vector or extract the diagonal elements from a matrix. Basic Syntax: The syntax for creating a diagonal matrix from a …

D = diag(v) returns a square diagonal matrix with vector v as the main diagonal. D = diag(v,k) places vector v on the k th diagonal. k = 0 represents the main diagonal, k > 0 is above the main diagonal, and k < 0 is below the main diagonal. Create a symbolic matrix with the main diagonal specified by the vector v.

Sep 9, 2015 · Easy way to generate a diagonal matrix from a vector? I have a vector v of size 1 x 5, and a diagonal matrix D of size 5 x 5. In my example, I have v = [0 1 2 3 4]. First question: I want to put the vector v on the diagonal of D, so that D(1,1) = …
