(Signal and System) An accelerometer is mounted at the top of a pile to
evaluate driving conditions. The digitized and stored signals are used to
compute the time history of velocity by the finite difference
approximation: v(n+1) = v(n) + a(n) Δt.Is this system transformation causal,
linear, time-invariant ? Let Δt=0.01 sec,general arbitrary signals with 128
points (e.g. a(n) = some constants or a(n) =some constants * n) as the
accelerometer records and use Matlab to show that the system is
linear or non-linear, time-invariant or time-variant by their definition
前面三行都不是重點，中間那邊題目雖然看的懂，但是我沒學過Matlab，這幾天有看了
張智星的書，要怎麼用語言寫出來還是有些困難，明天就要交了，懇請板上大神幫幫忙。
