What's the meaning of data structure and matlab function files (performance factor) in MATLAB Benchmark?

Hello Everyone,

In MATLAB built-in benchmark, there is a performance factor: Data structures and MATLAB function files, which are mearsured by speed of solving the ODE function. https://de.mathworks.com/help/matlab/ref/bench.html

What is meaning of Data structures and MATLAB function files here? and why they can be meaured by solving the 2. order ODE (van der pol equation) with ODE45?

Thanks!

Hello Li,

'bench' measures the execution speed of different MATLAB tasks and compares it to the speed of several other computers. There are three common way to store data in MATLAB: 1. Cell array; 2. Tables; 3. Struct arrays 4. MAT files, all of which MATLAB specific user defined data types. By the factor 'Data structures and MATLAB function files', the comparison in terms of factors such as speed of lading , reading or updatating data in these data structures is compared to across multiple machines to support the execution of ODE functionality.
