MAXMIN

Max or min value of a vector, or element-wise for N vectors

Description

This block finds the minimum/maximum values (parameter Min or Max) and accepts one or two inputs depending on the parameter Number of input vectors :

 Number of input vectors Input Operation 1 Vector The input must be a vector and the bloc output is the minimum/maximum value of the elements of its input vector. 2 Scalar The block output is the minimal or maximal scalar. 2 Vector All p input vectors must have the same length N. The block output is a vector with the same length N. The element output(i) of the output vector is min(input_1(i), input_2(i),..,input_p(i)) or max(input_1(i), input_2(i),..,input_p(i)), for `i=1..N`.

Parameters

• Min or Max

The function (min or max) to apply to the input.

Properties : Type 'vec' of size 1.

• Number of input vectors

The number of inputs to the block.

Properties : Type 'vec' of size 1.

• zero-crossing

Select to enable zero crossing detection to detect minimum and maximum values.

Properties : Type 'vec' of size 1.
