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.
