How add condition statement in an array? - MATLAB -

-

i'm working on mapping linking 2 coordinates , database huge. hence display part of work on had done.

question: add start , stop number together. if more 1,000,000 distance 100. else distance remain unchanged. store in single array.

really appreciate respond. :)

coding

clear; n = xlsread('regionall.xlsx',2); m = xlsread('regionall.xlsx',1); % list of coordinates      distance  = distance(m(start,3:4), m(to,3:4)); % coordinates distancekm = deg2km(distance); sum = n(:,1)+n(:,2);  %problem below l = 1:625     sum = n(l,1)+n(l,2);     if (sum>1000000)         = 100;     else         = distancekm(l,1);     end; end

excel data sample in variable n

start   stop    distance     13054   13055   0.017749628 13055   13001   0.152363674 560601  13043   0.063200318 560601  13042   0.036090789 560601  13041   0.021083981 560601  13037   0.04975146 560604  13031   0.047614849 560604  13030   0.051513765 560604  13029   0.076687991 560604  560605  0.060676069 560605  560606  0.046497332

first sum columns 1 & 2, store result in summatrix:

summatrix = n(:,1) + n(:,2);

then replace values > 1000000 in summatrix 100 using logical addressing:

summatrix(summatrix > 1000000) = 100;

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
