Hi, I want to build recursively defined, piecewise functions.
I first defined my zero-order functions
N40(xi)=piecewise(0<xi and xi<=1);
N50(xi)=piecewise(1<xi and xi<=2);
and I can plot them with desired result
but, how do I combine them, to make first order functions?
for instance, I want to have a function matematichally defined by:
N41 = (xi-1)*N40 + (2-xi)*N51
