  • The following arguments must be given:
  • xinput expressionvector
    yinput/output symbolvector; the symbol value is modified in place
  • COPY[x,y] is equivalent to y=x.

COPY[x,w] is equivalent to w=x:

Possible Issues  (2)

If the second argument is not a symbol, an error message is issued:

If the output symbol has been initialized to a vector, the input and output must have the same length:

To avoid this error, clear the existing output symbol.
