|
* Subtracts two `tf.Tensor`s element-wise, A - B. Supports broadcasting.
|
*
|
* ```js
|
* const a = tf.tensor1d([10, 20, 30, 40]);
|
* const b = tf.tensor1d([1, 2, 3, 4]);
|
*
|
* a.sub(b).print(); // or tf.sub(a, b)
|
* ```
|
*
|
* ```js
|
* // Broadcast subtract a with b.
|
* const a = tf.tensor1d([10, 20, 30, 40]);
|
* const b = tf.scalar(5);
|
*
|
* a.sub(b).print(); // or tf.sub(a, b)
|
* ```
|
* @param a The first `tf.Tensor` to subtract from.
|
* @param b The second `tf.Tensor` to be subtracted. Must have the same dtype as
|
* `a`.
