DSP Blockset

Create Diagonal Matrix

Create a square diagonal matrix from diagonal elements.

Library

Math Functions / Matrices and Linear Algebra / Matrix Operations

Description

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. The elements off the diagonal are zero.

• A = diag(D)          Equivalent MATLAB code
  

The output is always sample-based.
