功能:編寫(xiě)的計(jì)算皮亞諾相關(guān)系數(shù)
開(kāi)發(fā)語(yǔ)言:ruby
調(diào)用:correlate(x,y)
其中,x,y為需要計(jì)算相關(guān)度的向量
調(diào)用示例:
a = [3, 6, 9, 12, 15, 18, 21]
b = [1.1, 2.1, 3.4, 4.8, 5.6]
c = [1.9, 1.0, 3.9, 3.1, 6.9]
c1 = correlate(a,a) # 1.0
c2 = correlate(a,a.reverse) # -1.0
c3 = correlate(b,c) # 0.8221970228
puts c1#,c2,c3

Intro/: Directory containing introductory examples.
HelloWorld.c A simple program that draws a box and writes "Hello World" in
HelloWorld.f it.
data The data file for the introductory progressive example.
Lines.c Reads the data from file "data" and plots just the curve with
Lines.f no labels, viewport or anything indicating quantity or units.
Viewport.c Restricts the graph to a viewport and frames the viewport,
Viewport.f leaving the remainder of the area for labels, etc.
CharLbls.c Adds labels for the chart title, X-axis title, and Y-axis
CharLbls.f title.
Tics.c Adds tic marks to the viewport edges, but since clipping was
Tics.f not set correctly, tics extend outside the viewport.
Clip.c Sets clipping such that tic marks are clipped at the viewport
Clip.f boundaries.
TicLabels.c Adds numeric tic labels to the graph this is the final
TicLabels.f installment of the progressive example.
