role of "out" parameter in torch.matmul()

[sachinlodhi]

I was reading tensor tutorial:)
and found this optional parameter out in the torch.matmul(). Can please anyone tell what is the exact use of this parameter?

hi @sachinlodhi the "out" parameter specifies the tensor you want to store the result of the matrix multiplication. In the screenshot you posted, it would be save the matmul between tensor and tensor.T in y3. Instead of creating a new variable to hold the value of the matmul, you are doing it inline. I hope this helps.
