Through

Through[p[f,g,][x,y,]]

gives p[f[x,y,],g[x,y,],].

Through[expr,h]

performs the transformation wherever h occurs in the head of expr.

Details

  • Through distributes operators that appear inside the heads of expressions.
  • Parallelize[Through[p[f,g,][x,y,]]] computes Through[p[f,g,][x,y,]] in parallel on all subkernels. »

Basic Examples  (2)

Apply all functions in a list to the same argument:

Apply a sum of functions by forming the sum of the individual applications:

Scope  (2)

By default, the operation is performed for any function in the head:

Perform the operation only if the head is a sum of terms:

Applications  (2)
