Relational operators MATLAB

MATLAB also ofiFers relational or comparison operators that allow for the testing of relative magnitude of various aiguments. These relational operator are shown in Table 15.11. 

The last part of this section lists a few standard MATLAB operations, functions, and commands, collected into groups, together with short descriptions. This may help our readers to more easily find and use built-in MATLAB functions in their own MATLAB program codes. Please note that our MATLAB function descriptions below are very few and very short by necessity. The user should use the help. . . command to find the full length MATLAB reference guide entry for each MATLAB function when the need arises. This will help our readers use the full power and functionality of MATLAB commands and will enable them to browse for and find related built-in MATLAB functions. 

In the scope of the thesis, a steady-state model of polymer electrolyte membrane fuel cell was made by Matlab. The model was based on simplified chemical and electrical equations. The most important performance related parameters, namely operation temperature and pressure, were parametrically investigated. Output voltage, electrical output power, heat generation, material inputs and outputs, and efficiencies according to first and second law of thermodynamics were plotted by the change of temperature and pressure against current density. 

Almost all operations in MATLAB are performed in double-precision arithmetic conforming to IEEE Standard 754 (double precision calls for 52 mantissa bits). This represents the highest degree of resolution by which MATLAB can see two very close numbers as two different entities. The following examples illustrate the concept of floating point-related computational problems.
