DSP Blockset

Matrix Support

The DSP Blockset takes full advantage of the matrix format of Simulink. Some typical uses of matrices in DSP simulations are

• General two-dimensional array

• A matrix can be used in its traditional mathematical capacity, as a simple structured array of numbers. Most blocks for general matrix operations are found in the Matrices and Linear Algebra library.

• Factored submatrices

• A number of the matrix factorization blocks in the Matrix Factorizations library store the submatrix factors (such as lower and upper submatrices) in a single compound matrix. See the LDL Factorization and LU Factorization blocks for examples.

• Multichannel frame-based signal

• The standard format for multichannel frame-based data is a matrix containing each channel's data in a separate column. A matrix with three columns, for example, contains three channels of data, one frame per channel. The number of rows in such a matrix is the number of samples in each frame.

See the following sections of the DSP Blockset User's Guide for more information about working with matrices:
