thank you but

in the caffe/src/caffe/proto/caffe.proto:

support two inputs

so how can i realize (N*C*W*H) * (N*C)?

message ScaleParameter {

// The first axis of bottom[0] (the first input Blob) along which to apply

// bottom[1] (the second input Blob). May be negative to index from the end

// (e.g., -1 for the last axis).

//

// For example, if bottom[0] is 4D with shape 100x3x40x60, the output

// top[0] will have the same shape, and bottom[1] may have any of the

// following shapes (for the given value of axis):

// (axis == 0 == -4) 100; 100x3; 100x3x40; 100x3x40x60

// (axis == 1 == -3) 3; 3x40; 3x40x60

// (axis == 2 == -2) 40; 40x60

// (axis == 3 == -1) 60

// Furthermore, bottom[1] may have the empty shape (regardless of the value of

// "axis") -- a scalar multiplier.

optional int32 axis = 1 [default = 1];

// (num_axes is ignored unless just one bottom is given and the scale is

// a learned parameter of the layer. Otherwise, num_axes is determined by the

// number of axes by the second bottom.)

// The number of axes of the input (bottom[0]) covered by the scale

// parameter, or -1 to cover all axes of bottom[0] starting from

`axis`

.// Set num_axes := 0, to multiply with a zero-axis Blob: a scalar.

optional int32 num_axes = 2 [default = 1];

}
