Tutorial: Operators and Ext Module

This tutorial will go through the operators and Ext module. The operators in Owl are implemented using functors. However, you do not need to work with functors directly in order to use the operators.

Basic Operators

The operators have been included in each Ndarray and Matrix module. The following table summarises the operators currently implemented in Owl.

Operator	Example	Operation	Dense/Sparse	Ndarray/Matrix
+	x + y	element-wise add	both	both
-	x - y	element-wise sub	both	both
*	x * y	element-wise mul	both	both
/	x / y	element-wise div	both	both
+	x + y	element-wise add	both	both
