Generate matrix with Toeplitz symmetry
Math Functions / Matrices and Linear Algebra / Matrix Operations
The Toeplitz block generates a Toeplitz matrix from inputs defining the first column
and first row. The top input (
Col) is a vector containing the values
to be placed in the first column of the matrix, and the bottom
Row) is a vector containing the values to be placed in the
first row of the matrix.
y = toeplitz(Col,Row) % Equivalent MATLAB code
The other elements of the matrix obey the relationship
y(i,j) = y(i-1,j-1)
and the output has dimension
[length(Col) length(Row)]. The y(1,1)
element is inherited from the
Col input. For example, the following
Col = [1 2 3 4 5] Row = [7 7 3 3 2 1 3]
produce the Toeplitz matrix
When you select the Symmetric check box, the block generates a
symmetric (Hermitian) Toeplitz matrix from a single input,
defining both the first row and first column of the matrix.
y = toeplitz(u) % Equivalent MATLAB code
The output has dimension
[length(u) length(u)]. For example, the
Toeplitz matrix generated from the input vector
[1 2 3 4] is
The Toeplitz block supports real and complex floating-point and fixed-point inputs.
When selected, enables the single-input configuration for symmetric Toeplitz matrix output.
When you generate a symmetric Toeplitz matrix with this block, if the input vector is complex, the output is a symmetric Hermitian matrix whose elements satisfy the relationship
For fixed-point signals the conjugate operation could result in an overflow. When you select this parameter, overflows saturate. This parameter is only visible with the Symmetric parameter is selected. This parameter is ignored for floating-point signals.
