COPY

LinearAlgebra`BLAS`

COPY

COPY[x,y]

copies the contents of the vector x to the vector y.

詳細とオプション

To use COPY, you first need to load the BLAS Package using Needs["LinearAlgebra`BLAS`"].
The following arguments must be given:
x input expression vector

y input/output symbol vector; the symbol value is modified in place
COPY[x,y] is equivalent to y=x.

例 (1)

Load the BLAS package:

Wolfram Language code: Needs["LinearAlgebra`BLAS`"]

Assign a vector to y:

Wolfram Language code:

COPY[{1, 2, 3}, y];
y

Scope (4)

A real vector :

Wolfram Language code:

COPY[{1.2, -2.3, 4.5}, y];
y

A complex vector:

Wolfram Language code:

COPY[{1.2 + 2.3 I, 3.1 I}, z];
z

An arbitrary-precision vector:

Wolfram Language code:

COPY[{1\`20,2,3},y];
y

A symbolic vector:

Wolfram Language code:

COPY[{a, b, c}, s];
s

Properties & Relations (1)

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

Wolfram Language code:

x = RandomReal[1, {5}];
COPY[x, w];
w == x

Possible Issues (2)

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

Wolfram Language code: COPY[x, {2, 3, 4}]

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

Wolfram Language code:

COPY[{1, 2}, y];
y

To avoid this error, clear the existing output symbol.

Wolfram Language code:

Clear[y]
COPY[{1, 2, 3}, y]
