Tag for questions about packed arrays. Packed Arrays are data structures that can be seen as monolithic blocks containing a single data type, particularly Integers and Reals. Many functions operate very efficient on packed arrays. Questions may deal with packed array generation, conversion, and ...
A simple sounding question with a few sub questions: What is the difference between unpacked vs packed array? Are packed arrays more space efficent, how much so? Are packed arrays more time ...
Packed arrays are very useful because they save memory and generally allow speedier and more efficient calculation times. If a list of data currently stored as a packed array is unpacked, it can slow ...
I have the following code to construct a tridiagonal matrix: ...
When you pack lists there is an overhead therefore packing a list with, say, 2 elements is likely to cost more than you get back in efficiency. Mathematica has default list lengths for which functions ...
Consider the following example, which generate two identical arrays. Why sometimes the array is packed and sometimes it doesn't? And why they perform differently? Here the arrays are packed: ...
