# ipynb notebook for Beezer's Linear Algebra supplement

I'm reading Beezer's Sagemath workbook that accompanies his Linear Algebra book. He says there is a Sagemath format workbook that is more usable than the pdf. I've searched Everywhere including his page and every referenced page, but can't find it to download. Anyone know where it is? I don't know why he'd mention there is an ipynb notebook but make it impossible to find ðŸ˜€
