Output the minimum or maximum input value.

Description

The FixPt MinMax block is a masked S-function that outputs either the minimum or the maximum element of the inputs. You can choose which function to apply with the Function parameter list.

You specify the number of input ports with the Number of input ports parameter. If the block has one input port, the input must be a scalar or a vector. The block outputs a scalar equal to the minimum or maximum element of the input vector. 

If the block has multiple input ports, the non-scalar inputs must all have the same dimensions. The block expands any scalar inputs to have the same dimensions as the non-scalar inputs. The block outputs a signal having the same dimensions as the input. Each output element equals the minimum or maximum of the corresponding input elements.

For a detailed description of all other block parameters, refer to Block Parameters.

Parameters and Dialog Box

Open

• Function - The function to apply to the input.

• Number of input ports - The number of inputs to the block.

• Output data type and scaling - Specify the output data type and scaling via the dialog box, or inherit the data type and scaling from the driving block or by back propagation.

• Output data type - Any data type supported by the Fixed-Point Blockset.

• Output scaling - Radix point-only or slope/bias scaling. These scaling modes are available only for generalized fixed-point data types.

• Lock output scaling so autoscaling tool can't change it - If checked, Output scaling is locked. This feature is available only for generalized fixed-point output.

• Round toward - Rounding mode for the fixed-point output.

• Saturate to max or min when overflows occur - If checked, fixed-point overflows saturate. Otherwise, they wrap.

• Override data type(s) with doubles - If checked, the Output data type is overridden with doubles.

• Log minimums and maximums - If checked, minimum and maximum simulation values are logged to the workspace.
