Each global vector will have 5 elements with corresponding values as ordered above.6. Octave script fileThe script file containing a Function with a single input argument usually looks likefunction resultScalar = StrurelOctave (XP)# Uses only vector notation to access values of Variables and Parameters.# The sequence in input vector XP is predefined by Stochastic Model. resultScalar = XP(4)*(pi/4)*XP(2)*XP(3)^2 - XP(5)*XP(1);endfunctionHere elements of input vector %u2019XP%u2019 containing values from global vector v_XP_ can be accessed directly by an index, as is ordered in Stochastic Model of STRUREL.Alternatively, the assigned global names may be used also inside of function
