Final answer:
A multidimensional array consists of multiple arrays combined into a single structure. An interferometer array used in astronomy is an example of a multidimensional array.
Step-by-step explanation:
A multidimensional array is like several arrays of the same type put together. A practical example of this concept is an interferometer array, which is a combination of multiple radio dishes arranged to work in unison. Such an array functions as a large number of two-dish interferometers, allowing for detailed astronomical observations over wider areas than a single dish could cover.
A interferometer array is like several arrays of the same type put together. An example of an interferometer array is a combination of multiple radio dishes to, in effect, work like a large number of two-dish interferometers. Each array collects data and combines it to enhance the resolution and sensitivity of the observations.
