convmtx (MathScript Function) (Windows, Not in Base Package)
Member of the filter design class.
Syntax
c = convmtx(a, b)
Description
Computes the convolution matrix of an input vector.
Inputs
| Name | Description |
| a | Specifies the input vector. If a is a column vector and d is a column vector of length b, then convmtx(a, b)*d is the same as conv(a, d). If a is a row vector and d is a row vector of length b, then d*convmtx(a, b) is the same as conv(d, a). |
| b | Specifies the size of the output matrix. |
Outputs
| Name | Description |
| c | Returns the convolution matrix. |
Examples
y = convmtx(1:10, 5)
