Multi-view Triangulation using three cameras

In Compute Vision Toolbox examples, I can only see it has been used for a single camera capturing a scene from multiple views.
I have three images of a scene captured by three different cameras. Would it be useful to use Multi-view Triangulation function (triangulateMultiview)?
It appears that triangulateMultivew takes intrinsic and extrinsic camera parameters of a single camera (I could not find a way to look how triangulateMultiview function is implemented inside MATLAB). How would I feed these parameters from three different cameras to this (triangulateMultiview) function?
Is there any alternate solution to my problem?

There is a way to meet your requirements, only the camera projection matrix and the corresponding image points can complete the 3D reconstruction.
edit triangulateMultiview.m
worldPoints = vision.internal.triangulateMultiViewPoints(pointTracks, cameraMatrices)
