IBM ILOG CPLEX Optimization Studio vs. MATLAB

In my opinon, if the problem is less than 5000 variables, one should try to solve with free available solver rather than directly going for a commercial license of IBM CPLEX Optimization Studio. In my opinion, if the priority is not in terms of solving time with higher number of variables, even then one can go for free solvers like CBC, IPOPT, SCIP. In my opinion, if priority is solving time and number of variables is also high, only in that case one should prefer going for a commercial license.

Engineering, mathematical modeling, and machine learning are all fields where MATLAB will shine. It's fast, reliable, and relatively easy to use. MATLAB is the de facto standard when it comes to producing high-quality plots. If you need to deal with large data sets, and not take forever processing them, MATLAB may very well be the tool for you!

• Linear Programming
• Mixed-Integer Linear Programming
• Non-Linear Convex-Optimization
• Visualization
• Shadow Price Analysis
• Parameter Tuning

• Has robust and easy-to-use debugging tools that can help one identify problems in one's codes.
• Rich, well-developed and efficient library of mathematical and statistical functions that one might need to develop models or perform statistical analysis.
• A very active online user community that is a great resource in terms of seeking help when you hit a snag.
• Great help literature (and sometimes videos too) on all tools making it possible for all to train themselves.

• Data handling from different sources like Note Pad, etc.
• Large size of MILP problems.
• Various parameters to set.

• MATLAB should have a full free version (without time limit) in order to be more accessible and thus have a greater user community.
• The idea of having toolboxes to work directly with hardware (microcontrollers, single-board computers) is great, but one can tell it isn't updated very frequently and there isn't as much documentation available as with more common resources.
• Our organization had a lot of trouble getting our network licenses to work properly and there wasn't any local service provider that could help us get it to work faster.

It's nice to use and with good optimization.

The best thing about MATLAB is the variety of research and development fields it supports. The reason for this rating is that it is best used for medical images enhancement and signal processing, it is also used for speech to text conversion. This tool server is best when the demand is for machine learning.

Honestly, to say, I never contacted CPLEX but used its forum to know/clarify any issues I faced.

The built-in search engine is not as performing as I wish it would be. However, the YouTube channel has a vast library of informative video that can help understanding the software. Also, many other software have a nice bridge into MATLAB, which makes it very versatile. Overall, the support for MATLAB is good.

Compared with MATLAB, CPLEX is a more user-friendly and simpler structure for writing models. This one also has a good return on investment.

The commands and coding language of MATLAB reads a lot more in plain English as opposed to all the periods and other special characters that are needed when typing in Python or Java. Additionally MATLAB has several different function packages that can solve all different categories of problems so you don't have to make a bunch of different code scrips from scratch.

• Better for price.
• Many model parameters/features.
• No visualization.

• MATLAB has made me a better coder. I can see the code behind inbuilt functions which helps me improve my own coding.
• The various features offered in the software helped me to understand new topics in a relatively short span of time.
• MATLAB has a rich forum and library which allows exchange of ideas and info with other users. This has certainly broadened my horizon.
