2、spline函數，各個(gè)參數的含義？

spline函數的參數的含義主要如下：

Cubic spline data interpolation

Syntax

s = spline(x,y,xq)

pp = spline(x,y)

Description

s = spline(x,y,xq) returns a vector of interpolated values s corresponding to the query points in xq. The values of s are determined by cubic spline interpolation of x and y.

s = spline(x,y,xq)返回與xq中的查詢(xún)點(diǎn)對應的內插值s的向量。 s的值由x和y的三次樣條插值確定。

xq是使用MATLAB畫(huà)模擬信號圖時(shí)，坐標軸的范圍以及坐標點(diǎn)之間的間隔。這個(gè)間隔應該足夠密集。

pp = spline(x,y) returns a piecewise polynomial structure for use by ppval and the spline utility unmkpp.

pp = spline(x,y)返回一個(gè)分段多項式結構，供ppval和樣條函數unmkpp使用。

Spline Interpolation of Sine Data

Use spline to interpolate a sine curve over unevenly-spaced sample points.

x = [0 1 2.5 3.6 5 7 8.1 10];

y = sin(x);

xx = 0:.25:10;

yy = spline(x,y,xx);

plot(x,y,'o',xx,yy)

Spline Interpolation of Distribution with Specified Endpoint Slopes

Use clamped or complete spline interpolation when endpoint slopes are known. This example enforces zero slopes at the end points of the interpolation.

當已知端點(diǎn)斜率時(shí)，使用夾緊或完整的樣條插值。 此示例在插值的結束點(diǎn)強制執行零斜率。

x = -4:4;

y = [0 .15 1.12 2.36 2.36 1.46 .49 .06 0];

cs = spline(x,[0 y 0]);

xx = linspace(-4,4,101);

plot(x,y,'o',xx,ppval(cs,xx),'-');

Extrapolation Using Cubic Spline

Extrapolate a data set to predict population growth.

Create two vectors to represent the census years from 1900 to 1990 (t) and the corresponding United States population in millions of people (p).

推斷數據集以預測人口增長(cháng)。

創(chuàng )建兩個(gè)向量來(lái)表示1900年至1990年（t）的人口普查年和數百萬(wàn)人的相應美國人口（p）。

t = 1900:10:1990;

p = [ 75.995 91.972 105.711 123.203 131.669 ...

150.697 179.323 203.212 226.505 249.633 ];

Extrapolate and predict the population in the year 2000 using a cubic spline.

spline(t,p,2000)

Spline Interpolation of Angular Data（角度數據的樣條插值）

Generate the plot of a circle, with the five data points y(:,2),...,y(:,6) marked with o's. The matrix y contains two more columns than does x. Therefore, spline uses y(:,1) and y(:,end) as the endslopes. The circle starts and ends at the point (1,0), so that point is plotted twice.

生成一個(gè)圓的圖，其中五個(gè)數據點(diǎn)y（：，2），...，y（：，6）用o標記。 矩陣y包含比x多兩列的列。 因此，樣條曲線(xiàn)使用y（：，1）和y（：，end）作為endslopes。 圓圈在點(diǎn)（1,0）處開(kāi)始和結束，因此該點(diǎn)被繪制兩次。

x = pi*[0:.5:2];

y = [0 1 0 -1 0 1 0;

1 0 1 0 -1 0 1];

pp = spline(x,y);

yy = ppval(pp, linspace(0,2*pi,101));

plot(yy(1,:),yy(2,:),'-b',y(1,2:5),y(2,2:5),'or')

axis equal

Spline Interpolation of Sine and Cosine Data

Use spline to sample a function over a finer mesh.

Generate sine and cosine curves for a few values between 0 and 1. Use spline interpolation to sample the functions over a finer mesh.

使用樣條曲線(xiàn)在更精細的網(wǎng)格上對函數進(jìn)行采樣。

為0到1之間的幾個(gè)值生成正弦和余弦曲線(xiàn)。使用樣條插值在更精細的網(wǎng)格上對函數進(jìn)行采樣。

x = 0:.25:1;

Y = [sin(x); cos(x)];

xx = 0:.1:1;

YY = spline(x,Y,xx);

plot(x,Y(1,:),'o',xx,YY(1,:),'-')

hold on

plot(x,Y(2,:),'o',xx,YY(2,:),':')

hold off

Data Interpolation Using spline and pchip

Compare the interpolation results produced by spline and pchip for two different functions.

Create vectors of x values, function values at those points y, and query points xq. Compute interpolations at the query points using both spline and pchip. Plot the interpolated function values at the query points for comparison.

x = -3:3;

y = [-1 -1 -1 0 1 1 1];

xq1 = -3:.01:3;

p = pchip(x,y,xq1);

s = spline(x,y,xq1);

plot(x,y,'o',xq1,p,'-',xq1,s,'-.')

legend('Sample Points','pchip','spline','Location','SouthEast')

In this case, pchip is favorable since it does not oscillate as freely between the sample points.

Perform a second comparison using an oscillatory sample function.

x = 0:25;

y = besselj(1,x);

xq2 = 0:0.01:25;

p = pchip(x,y,xq2);

s = spline(x,y,xq2);

plot(x,y,'o',xq2,p,'-',xq2,s,'-.')

legend('Sample Points','pchip','spline')

When the underlying function is oscillatory, spline captures the movement between points better than pchip.
