cv.projectPoints: Wrong number of arguments

[X1l10on88]

MATLAB 2015a GCC 4.7 mexopencv: current branch OpenCV 3.4.1

Error:

imagePoints = cv.projectPoints(src2, rvec, tvec, K, distCoeffs) Error using projectPoints Wrong number of arguments

opencvmex compiled without warnings or errors and others cv. functions works properly.

Distortion coefficients param is an option, not required input (defaults to zero ceoffs).

So the call should be:

imagePoints = cv.projectPoints(src2, rvec, tvec, K, 'DistCoeffs',distCoeffs);

Solved, thanks!
