J2ME中MATLAB的interp1函数的实现

问题描述

我希望实现在J2ME或JAVA中的MATLAB中可用的interp1、1-D数据插值(表查找)功能.这是链接

J2ME或JAVA中是否有已经实现相同功能的库?如果没有，有人可以帮助我在J2ME或JAVA中实现interp1功能吗?

解决方案

如果在interp1函数的语法中为方法参数选择了"linear"，则我刚刚发现了用于线性插值的方法，即:interp1(x， y，xi，'linear').这是在multigraph包中提供的LinearInterpolator类的interp(double x)方法中实现的.链接在下面

如果您下载软件包并打开LinearInterpolator.java文件，则可以找到代码.下载软件包的链接是

i am looking to implement the interp1, 1-D data interpolation (table lookup), function available in MATLAB in J2ME or JAVA. here is the link

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/interp1.html

Is there any library available in J2ME or JAVA which has already implemented the same function ? If not can anybody help me in implementing interp1 function in J2ME or JAVA ?

解决方案

i just found out the method used for linear interpolation if 'linear' is selected for method parameter in the syntax of interp1 function, which is : interp1(x,y,xi,'linear'). This is implemented in the method interp(double x) of class LinearInterpolator which is present in multigraph package. the link is below

http://multigraph.sourceforge.net/multigraph/javadoc/multigraph/LinearInterpolator.html

if u download the package and open the file LinearInterpolator.java u can find the code. The link to download the package is
