Nand

Logical nand of inputs

Description

The output is $\mathrm{true}$ if at least one input is $\mathrm{false}$, otherwise the output is $\mathrm{false}$.

The Use vector boolean parameter selects the type of inputs.

 • If $\mathrm{false}$ (the default), the block has two boolean inputs, $\mathrm{u1}$ and $\mathrm{u2}$.
 • If $\mathrm{true}$, the block has a single boolean vector input, $u$, and the Signal size parameter sets the dimension of $u$. Signal size must be greater than $1$.
