Name

---

      SYMASYM

Purpose

---

      Resolve an array into symmetric & anti-symmetric components.

Category

---

Calling Sequence

---

      symasym, in, sym, asym

Inputs

---

      in = input array (1-d or 2-d). in

Keyword Parameters

---

Keywords

---

        /X means do symmetry/antisymmetry in X dimension.
        /Y means do symmetry/antisymmetry in Y dimension.
            These keywords only apply to 2-d data.

Outputs

---

      sym = symmetric component of in. out
      asym = anti-symmetric component of in. out

Common Blocks

---

Notes

---

      Notes: A set of radially sym/asym components for a
        2-d array may be obtained as follows:
        symasym,z,sx,sy,/x
        symasym,z,sy,sy,/y
        sym = (sx+sy)-(ax+ay)
        asym = (sx-sy)-(ax-ay)
