Detailed Description

Binary element-wise subtraction of two tensor expressions.

Used to build a lazily evaluated Binary<Subtraction, Subtrahend, Minuend> expression. Computation is deferred until forward() is called or assigned to a Tensor. Supports broadcasting and type promotion.

Example: Subtraction

Tensor A(float32, {2, 2}); A.initialize();
A[0, 0] = 5; A[0, 1] = 7;
A[1, 0] = 9; A[1, 1] = 11;
 
Tensor B(float32, {2, 2}); B.initialize();
B[0, 0] = 1; B[0, 1] = 2;
B[1, 0] = 3; B[1, 1] = 4;
 
auto C = A - B;
std::cout << C.forward();
// Output: [[4, 5], [6, 7]]
