How to use 'jar' in matlab m file?

I have the 'jar' file and the usage of (the classes contained in jar) in java code is like the following:

[code java] import kr.hyosang.coordinate.*;

........

CoordPoint pt = new CoordPoint(126.97553009053178, 37.56456569639763);

CoordPoint ktmPt = TransCoord.getTransCoord(pt, TransCoord.COORD_TYPE_WGS84, TransCoord.COORD_TYPE_KTM);

[/code]

------------------------------------------------------------------

And this is my matlab code which has a problem to run.

clc; clear all;

javaaddpath('TransCoord.jar')

import kr.hyosang.coordinate.*;

CP=CoordPoint

methods(CP)

pt=CP(126.97553009053178, 37.56456569639763)

clear import

clear java

-----------------------------------------------------

I know nothing whatever about JAVA. But the only ting I want to do is

CoordPoint pt = new CoordPoint(126.97553009053178, 37.56456569639763);

CoordPoint ktmPt = TransCoord.getTransCoord(pt, TransCoord.COORD_TYPE_WGS84, TransCoord.COORD_TYPE_KTM);

to run these two lines in my matlab code.

Hi,

this should work right away:

pt = CoordPoint(126.97553009053178, 37.56456569639763);
ktmPt = TransCoord.getTransCoord(pt, TransCoord.COORD_TYPE_WGS84, TransCoord.COORD_TYPE_KTM);

or let us know what the error message is :).

Thanks for your answer. I have tried as you mentioned. It works without any comfile error. And when I try checking the result value of ktmpt by using ktmpt without semicoln, matlab just shows me "ktmpt =

kr.hyosang.coordinate.CoordPoint@106f29c8"

This is not what I want to get. Actually, that code is to transform Coordinate system. So result of the code should be two real values. eg)512.12 353.1234 something like this.

[Malcolm Lidierth]

ktmpt is a Java object: an instance of kr.hyosang.coordinate.CoordPoint with hashCode 106f29c8.

Extract your data using the object's methods. To get a list of them, type:

>> methods(ktmpt)

at the MATLAB prompt.

Thank you, Malcolm Lidierth. Unfortunately, I am not used to using java. Even though I type 'methods(ktmpt)', I don't konw how to use it. You can download the 'jar' file on

http://hyosang.kr/269

Could you test using download file?

[Titus Edelhofer]

As Malcolm said, with methods(ktmPt) you should get a list of methods. I could imagine there are methods called getX and getY or something similar. In this case simply do

x = ktmPt.getX();

Thank you, Titus Edelhofer . When I type methods(ktmPt), I get the following list:

Methods for class kr.hyosang.coordinate.CoordPoint:

CoordPoint convertCONG2BESSEL convertWGS2UTM equals wait clone convertKTM2BESSEL convertWGS2WCONG getClass convertBESSEL2CONG convertTM2BESSEL convertWGS2WKTM hashCode convertBESSEL2KTM convertUTM2WGS convertWGS2WTM notify convertBESSEL2TM convertWCONG2WGS convertWKTM2WGS notifyAll convertBESSEL2WGS convertWGS2BESSEL convertWTM2WGS toString

And I have tried all the possible cases, but I couldn't get the result I want.
