Multiplication Keep default-Element-wise [K.*u]

Icon Shape Select rectangular or roundList of signs Input one or more + or - signs

*The symbol | puts space between ports

Numerator Input coefficients from the Numeratorof Tfn. Enclose values in []

Denominator Input coefficients from the Denominator of Tfn. Enclose values in[]

Absolute Tolerance Keep default-autoFields A and B Coefficient matrices from State

Equation xdot = [A]x + [B]uFields C and D Coefficient matrices from output

Equation y = [C]x + [D]uInitial Conditions Initial Condition value i.e. t = 0Absolute Tolerance Keep Default-autoVariable Name Input a variable nameLimit data points to last Keep default- inf infiniteDecimation Keep default-"1" Sample Time Keep default- -1 will inherit sample

rate from the driving blockSave Format Select Array
