Find minimum values of input or sequence of inputs
The dsp.Minimum
object finds the minimum value
of an input or sequence of inputs.
To compute the minimum value of an input or sequence of inputs:
Define and set up your System object™. See Construction.
Call step
to compute the minimum according to the
properties of dsp.Minimum
. The behavior of step
is
specific to each object in the toolbox.
Starting in R2016b, instead of using the step
method
to perform the operation defined by the System
object, you can
call the object with arguments, as if it were a function. For example, y
= step(obj,x)
and y = obj(x)
perform
equivalent operations.
The Running
mode in the dsp.Minimum
System
object will
be removed in a future release. To compute the running minimum in MATLAB^{®},
use the dsp.MovingMinimum
System
object instead.
min = dsp.Minimum
returns
an object, min
, that computes the value and/or
index of the minimum elements in an input or a sequence of inputs
over the specified Dimension
.
min = dsp.Minimum('

, with each specified
property set to the specified value.

Condition that triggers resetting of running minimum Specify the event that resets the running minimum as one of  

Numbering base for index of minimum value Specify the numbering used when computing the index of the minimum value as starting from

Dimension to operate along Specify how the minimum calculation is performed over the data as one of 


Numerical dimension to calculate over Specify the integer dimension of the input signal over which the object finds the minimum. The
cannot exceed the number of dimensions in the input signal. This property
only applies when you set the Dimension property to
