Vector normalization along specified dimension
The Normalizer object performs vector normalization along rows, columns, or specified dimension.
To perform vector normalization:
H = dsp.Normalizer returns a normalization object, H, that normalizes the input over each column by the squared 2-norm of the column plus a bias term of 1e-10 used to protect against divide-by-zero.
H = dsp.Normalizer('PropertyName',PropertyValue, ...) returns a normalization object, H, with each property set to the specified value.
Type of normalization to perform
Specify the type of normalization to perform as 2-norm or Squared 2-norm. The 2-norm mode supports floating-point signals only. The Squared 2-norm supports both fixed-point and floating-point signals. The default is Squared 2-norm.
Real number added in denominator to avoid division by zero
Specify the real number to add in the denominator to avoid division by zero. The default is 1e-10. This property is tunable.
Dimension to operate along
Specify whether to normalize along Column , Row, or Custom. The default is Column.
Numerical dimension to operate along
Specify the one-based value of the dimension over which to normalize. The value of this parameter cannot exceed the number of dimensions in the input signal. This property applies when Dimension property is Custom. The default is 1.
|clone||Create normalization object with same property values|

This object implements the algorithm, inputs, and outputs described on the Normalization block reference page. The object properties correspond to the block parameters, except:
Treat sample-based row input as column — The block allows you to input a row vector and normalize the row vector as a column vector. The normalization object always normalizes along the value of the Dimension property.
The normalization object does not support the Minimum and Maximum options for data output.
