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);

Hello,

You should split the data into multiple smaller XML elements or chunks rather than trying to dump all values into a single TextNode. Refer to the following example to write in chunks:

chunkSize = 500;
docNode = com.mathworks.xml.XMLUtils.createDocument('LUT');
rootNode = docNode.getDocumentElement;
entry_node = docNode.createElement('sigmaLUT');

for i = 1:chunkSize:length(b)
    chunk = b(i:min(i+chunkSize-1, end));
    chunkNode = docNode.createElement('chunk');
    chunkNode.appendChild(docNode.createTextNode(sprintf('%i ', chunk)));
    entry_node.appendChild(chunkNode);
end

rootNode.appendChild(entry_node);
xmlwrite('sigmaLUT.xml', docNode);

I hope this helps with your query!
