Predict Broadcasted Dimensions
Description
bc_dim(x, y) gives the dimensions an array would have, as the result of an broadcasted binary element-wise operation between 2 arrays x and y.
Usage
bc_dim(x, y)
Arguments
x, y
|
an atomic or recursive array. |
Value
Returns an integer vector giving the broadcasted dimension sizes.
