- * This function comes from https://github.com/tensorflow/tfjs/blob/master/tfjs-core/src/ops/broadcast_util.ts#L18-L40
- * Returns the dimensions in the input shape that are broadcasted to
- * produce the provided output shape.
- *
- * The returned dimensions are 0-indexed and sorted. An example:
- * inShape = [4, 1, 3]
- * outShape = [5, 4, 3, 3]
- * result = [1]. Dimension 1 (2nd dimension of input) gets broadcasted 1 => 3.
