Description
The MinMax block outputs either the minimum or maximum element(s) of the input signals. Whether the block outputs the minimum or maximum values is determined by the value of the Function parameter.
The MinMax block ignores any input value that is equal to NaN, except when every input value is equal to NaN. When all input values are equal to NaN, the output is equal to NaN, either as a scalar or as the value of each element of the output vector.
Ports
Output
#
OUT_1
—
minimum or maximum values
scalar | vector | matrix
Details
When the unit has one input port, the output is a scalar equal to the minimum or maximum element of the input signals.
When the unit has several input ports, the output is a signal having the same dimensions as the Input. Each output element is equal to the minimum or maximum of the corresponding input elements.

Input
#
IN_1
—
Input signal
scalar | vector | matrix
Details
The input signal from which the unit outputs the maximum or minimum values.
-
When a 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.
-
When a block has several input ports, all non-scalar input parameters must have the same dimensions. The block extends any scalar input parameters to have the same dimensions as non-scalar input parameters. The unit outputs a signal having the same dimensions as the Input. Each output element is equal to the minimum or maximum of the corresponding input elements.
Dependencies
To support matrix input, it is necessary for the parameter Number of input ports set an integer greater than one. All non-scalar input parameters must have the same dimensions.

Output fixed-point type —
the output type of fixed-point numbers
Data type
Details
Specify the output type of fixed-point numbers.
Dependencies
To use this parameter, set for the parameter Output data type meaning Fixed-point.

Integer rounding mode —
rounding mode for fixed point operations
Ceiling | Convergent | Floor | Nearest | Round | Zero
Details
Select the rounding mode for fixed-point operations. You can choose:
-
Ceiling— rounds up both positive and negative numbers (towards positive infinity). -
Convergent— rounds the number to the nearest representable value. If the fractional part of the number ends in5, the number is rounded to the nearest even integer. -
Floor— rounds down both positive and negative numbers (towards negative infinity). -
Nearest— rounds the number to the nearest representable value. If the fractional part of the number ends in5, the number is rounded up (towards positive infinity). -
Round— rounds the number to the nearest integer. -
Zero— rounds the number towards zero.
The block parameters are always rounded to the nearest representable value.

Saturate on integer overflow —
method of action in case of overflow
Logical
Details
When this check box is selected, the value that goes beyond the type limits is reset to the maximum or minimum value that the selected data type can represent. Otherwise, overflow transfer occurs.
When this option is selected, saturation is applied to all internal operations in the block, not just to the output or result.
