how to save 1x3072 data without output truncated error?

I am facing problem of extracting a data of 1*3072 into xml file. The last data can be saved is no.2500. Output truncated error occurred ever since there. Can anybody help? Here is my code:

docNode = com.mathworks.xml.XMLUtils.createDocument('LUT'); xmlwrite(docNode) entry_node = docNode.createElement('sigmaLUT');

a= signal(:,1); b= abs(a)';

entry_node.appendChild(docNode.createTextNode(sprintf('%i',b))); docNode.getDocumentElement.appendChild(entry_node); xmlwrite(docNode) xmlwrite('sigmaLUT.xml',docNode);
