EXPAND Function

Standard Library function that expands an array into higher dimensions.

Usage

result = EXPAND(a, d, i)

Input Parameters

a—An array of n dimensions.

d— A vector specifying the dimensions for the new array.

i—A monotonically increasing vector of n indices into d specifying which of the new dimensions correspond to old dimensions: d(i) must equal SIZE(a, /Dimensions).

Returned Value

result—An array of dimensions d, the expansion of the input array.

Keywords

None.
