发帖数: 2334 | 1 an example of gibbs phenomenon: when you interpolate the
step function, the size of overshooting near the incontinuity
goes to the
product of a constant and the jump of step function.
this constant is about 9%(not sure ) theoretically.
I don't know what is Gibbs phenomenon wiggles.
BTW, who knows the constant in computation?
In my program, when I increased the number of interpolation basis,
the constant is only close to 14%. |
