What's are the parameters in detect() function?

I want to use function detect() to evaluate Faster R-CNN detector in Matlab and I have found this code on the Matlab website.

detect(detectorFasterRCNN,testData,'MinibatchSize',4);

But I can't find what is the 4th parameter in this function. I mean the number 4 in this function.

I would greatly appreciate any help. Thanks.

Refer to the MiniBatchSize input argument explanation of the detect documentation.

Minimum batch size, specified as the comma-separated pair consisting of 'MiniBatchSize' and a scalar value. Use the MiniBatchSize to process a large collection of images. Images are grouped into minibatches and processed as a batch to improve computation efficiency. Increase the minibatch size to decrease processing time. Decrease the size to use less memory.

In your above code, the number 4 refers to the Mini Batch Size i.e., the detect function processes 4 samples of testData at a time.
