+
+### Bug Fixes
+
+* use more Float64Array in decompositions ([0bd8f1b](https://github.com/mljs/matrix/commit/0bd8f1b))
+* **Matrix:** use Float64Array to improve performance ([9dfe983](https://github.com/mljs/matrix/commit/9dfe983))
+* **SVD:** use Float64Array to avoid deopt ([85acd13](https://github.com/mljs/matrix/commit/85acd13))
