(const Object lhs - const RealTensor rhs) -> RealTensor	Element-wise subtraction of Real tensors or tensor-scalar subtraction.

(const Object lhs - const ComplexTensor rhs) -> ComplexTensor

Element-wise subtraction of Complex tensors or tensor-scalar subtraction.

Subtracts one tensor from another element-wise, or subtracts a scalar from a tensor, or subtracts a tensor from a scalar.

For tensor-tensor subtraction:

• Both tensors must have the same shape.
• Result[i,j,k,...] = A[i,j,k,...] - B[i,j,k,...]

For tensor-scalar subtraction:

• The scalar is substracted from every element of the tensor.
• Result[i,j,k,...] = A[i,j,k,...] - s

For scalar-tensor subtraction:

• The output tensor is the scalar minus each element of the tensor.
• Result[i,j,k,...] = s - B[i,j,k,...].

Parameters

• rhs: Second operand: complex tensor or scalar.

Returns

A new complex tensor containing the element-wise difference.

Example

// Subtract two tensors
var A = filled_tensor([2, 3], 5.0, as_complex)
var B = filled_tensor([2, 3], 2.0, as_complex)
var C = A - B  // Each element is 5.0 - 2.0 = 3.0
print(C[0, 0])  // 3.0

// Subtract scalar from tensor
var D = filled_tensor([2, 2], 10.0, as_complex)
var E = D - 3.0  // Each element is 10.0 - 3.0 = 7.0
print(E[1, 1])  // 7.0

// Subtract tensor from scalar
var F = filled_tensor([2, 2], 2.0, as_complex)
var G = 10.0 - F  // Each element is 10.0 - 2.0 = 8.0
print(G[0, 1])  // 8.0

(const Object lhs - const RealTensor rhs) -> RealTensor

Element-wise subtraction of Real tensors or tensor-scalar subtraction.

Subtracts one tensor from another element-wise, or subtracts a scalar from a tensor, or subtracts a tensor from a scalar.

For tensor-tensor subtraction:

• Both tensors must have the same shape.
• Result[i,j,k,...] = A[i,j,k,...] - B[i,j,k,...]

For tensor-scalar subtraction:

• The scalar is substracted from every element of the tensor.
• Result[i,j,k,...] = A[i,j,k,...] - s

For scalar-tensor subtraction:

• The output tensor is the scalar minus each element of the tensor.
• Result[i,j,k,...] = s - B[i,j,k,...].

Parameters

• rhs: Second operand: real tensor or scalar.

Returns

A new real tensor containing the element-wise difference.

Example

// Subtract two tensors
var A = filled_tensor([2, 3], 5.0, as_real)
var B = filled_tensor([2, 3], 2.0, as_real)
var C = A - B  // Each element is 5.0 - 2.0 = 3.0
print(C[0, 0])  // 3.0

// Subtract scalar from tensor
var D = filled_tensor([2, 2], 10.0, as_real)
var E = D - 3.0  // Each element is 10.0 - 3.0 = 7.0
print(E[1, 1])  // 7.0

// Subtract tensor from scalar
var F = filled_tensor([2, 2], 2.0, as_real)
var G = 10.0 - F  // Each element is 10.0 - 2.0 = 8.0
print(G[0, 1])  // 8.0
