# fastRestartForLinearAnalysis

Fast restart for linear analysis

## Syntax

## Description

`fastRestartForLinearAnalysis(`

prepares the `model`

,'on')`model`

for single compilation workflows by turning fast
restart for linear analysis `'on'`

. Once a compiling function is called,
the model will remain compiled after the function is finished executing. Compiling functions
can then be later called without any additional compilations. If the linear analysis points
or block substitutions change with subsequent calls to compiling functions, the model is
recompiled.

`fastRestartForLinearAnalysis(`

prepares the `model`

,'on',`Name,Value`

)`model`

for single compilation workflows with additional
options specified by one or more `Name,Value`

pair arguments.

`fastRestartForLinearAnalysis(`

turns fast restart for linear analysis off and restores the model parameters to their
original value. Simulink`model`

,'off')^{®} does not let you close the `model`

while it is in a
complied state. Use this syntax to turn fast restart for linear analysis off before closing
the `model`

.

You can also click the link that appears on the top of the compiled Simulink model to turn `fastRestartForLinearAnalysis`

off. For more
information, see Tips.

## Examples

## Input Arguments

## Tips

Simulink does not let you close the

`model`

while it is in a compiled state. Turn fast restart for linear analysis off to close the`model`

. You can turn off`fastRestartForLinearAnalysis`

in one of the following ways.Use the syntax

`fastRestartForLinearAnalysis(model,'off')`

.Click the link that appears on the top of the Simulink model.

When fast restart for linear analysis is on, calling compiling functions does not automatically apply changes to state initial conditions. Therefore, you must configure the initial state using an operating point object rather than using parameters or workspace variables. For more information, see Linearize Model Using Multiple State Initial Conditions.
