Slider Gain

Vary a scalar gain using a slider

Description


The Slider Gain block allows you 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, Matrix Gain).

Dialog Box

Low
The lower limit of the slider range. The default is 0.
High
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 slider's left or right arrow, the current value changes by about 1% of the slider's 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's range.

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