Some examples of how MATLAB can be used in chemical engineering include: MATLAB has a number of functions that allow solving linear and nonlinear equations (fzero: for one variable alone, fsolve), optimizing a function (fmincon: constrained optimization, linprog: linear programming fminin or fminsearch: unconstrained optimization bintprog: binary and integer optimization), and solving differential equations (ode_) or partial differential equations (pdepe).
Within MATLAB, we have all the algebraic, statistical functions predefined along with plotting capabilities. Functions can be user-defined or typical operations such as equation solving or differential equations. A script is basically a number of operations that we want to perform in a certain sequence. Functions are a particular type of scripts that must begin with the word “function” at the top of them. m files that can be divided in two classes, scripts and functions. Much has been written about this popular software, more than 1500 books serving more than 1 million users.

MATLAB is one of the most used software packages in engineering in general and also in chemical engineering. Therefore, we can use the information in Excel to be loaded in MATLAB, Hysys or CHEMCAD or transferred back to Excel. Link Excel with other software – Excel has become a standard package so that a number of other specialized software use it as a source of information to report data since it is more user-friendly.This capability also allows the user to build relatively large equations that are used in several areas of the worksheet (e.g., polynomials for the esti¬mation of specific heat of components) and allows the user to read the calculations easily when looking at the formulas in the cells. This is a powerful tool that can save time for you without becoming an expert in programming as it opens the possibilities to run loops and conditionals on the background. Building functions in Visual Basic for Applications – Excel has built-in capability to generate customized functions using Visual Basic for Applications (VBA).
Solver is an add-in that needs to be activated to be used.

In this article, we highlight the most important tools and packages with their capabilities, based on the available professional experience of an author, available literature and discussions. The different packages can be applied to solve typical problems in mass and energy balance, fluid mechanics, heat and mass transfer, unit operations, reactor engineering, and process and equipment design and control. In fast everyday life, it is a considerable challenge for a chemical engineer to know which tool can serve best for solving a certain problem.
The field of chemical engineering is in constant change, so are available calculation tools and software packages. What is the Most Useful Software in Chemical Engineering? The List of Most Important Calculation Tools
