function v = schtrig (x, lev, rs)
//This function implements a multisignal Schmitt triggers with lev levels supplied as input.
//Calling Sequence
//v = schtrig (x, lev)
//v = schtrig (x, lev, rs)
//Parameters
//x: vector or matrix of real numbers
//lev: real number
//rs: default value 1
//Description
//This is an Octave function.
//This function implements a multisignal Schmitt triggers with lev levels supplied as input.
//The argument 1 is a matrix (or a vector) and this trigger works along its first dimension.
//Examples
//schtrig([0.2,-3,5],-4)
//ans =
// 0. 0. 1.
