What do I have to put in cameraParameters in order to for showExtrinsics to work?

Lets say I obtain extrinsic parameters for a camera somewhere else instead of Matlab's camera matlab camera calibration app, but I want to use Matlab to visualize where the camera is in space. A simple code below returns error,
cam = cameraParameters('RotationVectors',om,'TranslationVectors',T);
showExtrinsics(cam,'patternCentric');
Error using showExtrinsics/computeConvexHull (line 180)
Index exceeds matrix dimensions.
Error in showExtrinsics/parseInputs (line 155)
[wpConvHull, offset] = computeConvexHull(camParams);
Error in showExtrinsics (line 95)
[offset, wpConvexHull, extView, highlightIndex, numBoards, hAxes] = ...
What other information are necessary to put in the cameraParameters struct in order to visualize it?

You need the intrinsics too.
