You can use the row-major iterator by utilizing the RowMajor class as follows:
void operator()(matlab::mex::ArgumentList outputs, matlab::mex::ArgumentList inputs)
{
const matlab::data::TypedArray<double> data = std::move(inputs[0]);
// Option 1: Using explicit iterators
for (auto it = matlab::data::RowMajor::begin<double>(data);
it != matlab::data::RowMajor::end<double>(data);)
{
std::cout << *it++ << " ";
}
// Option 2: Using range-based for loop with writableElements
auto range = matlab::data::RowMajor::writableElements<double>(data);
for (const auto& elem : range) {
// ... Your code ...
}
}
Make sure to include "RowMajorIterator.hpp" in your header files, and add the appropriate include path when compiling:
mex yourfile.cpp -I"matlabroot/extern/include/MatlabDataArray"
replace 'matlabroot' with abosolute path of your 'matlabroot' in the above command.
