示例1: getFieldStartingRow
void PointMatcher<T>::DataPoints::removeField(const std::string& name, Labels& labels, MatrixType& data) const
{
const unsigned deleteId = getFieldStartingRow(name, labels);
const unsigned span = getFieldDimension(name, labels);
const unsigned keepAfterId = deleteId + span;
const unsigned lastId = data.rows() - 1;
const unsigned sizeKeep = data.rows() - keepAfterId;
const unsigned nbPoints = data.cols();
// check if the data to be removed at the end
if(keepAfterId <= lastId)
{
data.block(deleteId, 0, sizeKeep, nbPoints) = data.block(keepAfterId, 0, sizeKeep, nbPoints);
}
//Remove the last rows
data.conservativeResize(data.rows()-span, nbPoints);
// remove label from the label list
for(BOOST_AUTO(it, labels.begin()); it != labels.end(); ++it)
{
if (it->text == name)
{
labels.erase(it);
break;
}
}
