User Reference:SpatialFilter

Function

The SpatialFilter computes an instantaneous linear transformation of its input. This linear transformation is described by a transformation matrix, and applied for each sample separately, not linking data across different points in time.

Typically, the SpatialFilter's input is the unfiltered brain signal from the source module.

Parameters

SpatialFilter is a matrix defining the linear transformation applied to the filter's input signal. In this matrix, columns represent input channels, and rows represent output channels. Each matrix element defines a weight with which the respective input channel (column) enters into the respective output channel (row).

If the spatial filter is an identity filter -- not modifying its input --, then the SpatialFilter matrix is a unit matrix (square matrix with ones on the main diagonal, and all other elements zero).

States

None.
