create_scaling_matrix()

Eigen::MatrixXd MayaFlux::Kinesis::create_scaling_matrix

(

const std::vector< double > &

scale_factors

)

Create diagonal scaling matrix from per-axis factors.

Parameters

scale_factors

Scale value per dimension. Empty input returns 1x1 identity.

Returns

Diagonal scaling matrix (NxN where N = scale_factors.size())
