getbounds

Get bounds specified in Check block

Syntax

bnds = getbounds(blockpath)

Description

bnds = getbounds(blockpath) returns the bounds specified in the Check block specified by blockpath.

Examples

Get Bounds from Check Block

Retrieve bounds from a Check Step Response Characteristics block.

load_system('sldo_model1_stepblk');
allBlkReq = getbounds('sldo_model1_stepblk/Step Response');

Type allBlkReq{1} to view the cell array element.

allBlkReq{1}

ans = 
  StepResponseEnvelope with properties:

         InitialValue: 0
           FinalValue: 1
             StepTime: 0
             RiseTime: 5
          PercentRise: 80
         SettlingTime: 7
      PercentSettling: 1.0000
     PercentOvershoot: 10.0000
    PercentUndershoot: 1

Input Arguments

blockpath — Path to check block

string scalar | character vector

Check block to get bounds from, specified as a full block path inside single quotes (' '). A block path is of the form model/subsystem/block that uniquely identifies a block in the model. The Simulink^® model must be open.

Output Arguments

bnds — Bounds specified in Check block

cell array

The number of elements returned and objects they contain depends on the Check block type specified by blockpath.

• Check Step Response Characteristics: Cell array of one element that contains a sdo.requirements.StepResponseEnvelope object.

• Check Custom Bounds: Cell array of two elements — the first and second elements contain the following upper and lower bound values, respectively. Both elements are sdo.requirements.SignalBound objects.

• Check Against Reference: Cell array of one element that contains a sdo.requirements.SignalTracking object.

Note

Programmatically changing the bound values in the object returned does not update them in the Block Parameters dialog box.
