How to do sigmoid on OpenCV Mat?

Hi what is the best way to calculate sigmoid on an entire Mat? I've been unable to figure it out after looking at documentation. Thank you.

There's a SigmoidLayer available as part of the opencv_dnn module: https://docs.opencv.org/4.x/dc/d09/classcv_1_1dnn_1_1SigmoidLayer.html

Thank you. How can I access this from Java sorry?
