Slider Gain - Vary scalar gain using slider

Library

Math Operations

Description

Use the Slider Gain block to vary a scalar gain during a simulation using a slider. The block accepts one input and generates one output.

Data Type Support

Data type support for the Slider Gain block is the same as that for the Gain block (see Gain).

Parameters and Dialog Box

Low

Specify the lower limit of the slider range. The default is 0.

High

Specify the upper limit of the slider range. The default is 2.

The edit fields indicate (from left to right) the lower limit, the current value, and the upper limit. You can change the gain in two ways: by manipulating the slider, or by entering a new value in the current value field. You can change the range of gain values by changing the lower and upper limits. Close the dialog box by clicking the Close button.

If you click the left or right arrow of the slider, the current value changes by about 1% of the slider range. If you click the rectangular area to either side of the slider's indicator, the current value changes by about 10% of the slider range.

To apply a vector or matrix gain to the block input, consider using the Gain block.

Examples

The following demo models show how to use the Slider Gain block:

• aero_six_dof
