Replaces elements in y with elements in x.
The data types you wire to x and y determine the polymorphic instance to use.

Inputs/Outputs
yInc
—
yInc determines whether the VI skips elements in y for the calculation. The default is 1, meaning the VI does not skip any elements in y. yInc is an optional input. Note If you wire a value other than the default to yInc, the VI skips elements that have indexes that are multiples of the value you wire. If you wire a value that is greater than or equal to the number of elements in y, the VI uses only the first element in y for the calculation. If you wire a value that is less than 0, the VI reverses the order of the elements before it calculates the result.
xInc
—
xInc determines whether the VI skips elements in x for the calculation. The default is 1, meaning the VI does not skip any elements in x. xInc is an optional input. Note If you wire a value other than the default to xInc, the VI skips elements that have indexes that are multiples of the value you wire. If you wire a value that is greater than or equal to the number of elements in x, the VI uses only the first element in x for the calculation. If you wire a value that is less than 0, the VI reverses the order of the elements before it calculates the result.
x
—
x is the real source vector.
y
—
y is a real vector that supplies the default values for dcopy. The default is a vector with all elements equal to 0.
dcopy
—
dcopy is a real vector of the same size as y. dcopy returns the result from copying elements of x to y.
error
—
error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster. |
