Hat functions¶
Let’s define a set of 6 nodes (i.e., \(n=5\) in our formulas).
using FundamentalsNumericalComputation
t = [0, 0.075, 0.25, 0.55, 0.7, 1]
6-element Array{Float64,1}:
0.0
0.075
0.25
0.55
0.7
1.0
We plot the hat functions \(H_0,\ldots,H_5\).
plot([x->FNC.hatfun(x,t,k) for k=0:5],0,1,label="",
xlabel="\$x\$", ylabel="\$H_k(x)\$", title="Hat functions")
