# view

## Description

Use `view`

to graphically analyze the model and select a model
order reduction criteria from a model order reduction task created using `reducespec`

. For
`ModalTruncation`

and `SparseModalTruncation`

objects, you
can visualize modes (poles) based on their locations, damping and natural frequencies, or
normalized DC contributions. For the full workflow, see Task-Based Model Order Reduction Workflow.

`view(`

creates a
plot that helps you select the modal content of the reduced model. `R`

,`type`

)`R`

specifies the model order reduction (MOR) specification object. Use the
`type`

argument to specify these plot types.

`"mode"`

— Mode locations`"damp"`

— Mode damping and natural frequencies`"contrib"`

— Bar chart of normalized DC contributions

`view(`

plots the default plot type for the
model order reduction algorithm of `R`

)`R`

. For the modal truncation
method, this syntax plots the mode locations.

`view(___,Axes=AX)`

plots on the `Axes`

object in the current figure with the handle `AX`

. Use this input
argument after any of the input argument combinations in the previous syntaxes. For more
information about customizing axes, see ```
Axes
Properties
```

.

`view(`

returns help specific to the
model order specification object `R`

,"-help")`R`

. The returned help shows plot
types and syntaxes applicable to `R`

.
