Some important functions you should not forget!



In mathematical programming environment, it is really necessary for us to know various functions which can perform fundamental operations. I am sharing a curated list of functions which are very much useful while programming mathematical models in MATLAB.

Fundamental mathematical functions you should know.


Let's take some examples to experience the use of these functions -

Commands used in simple mathematical equations. 


Variables 'a' , 'b' are defined by user, which are known as independent variables. Variables 'x' and 'y' are output of some mathematical operation of 'a' and 'b', which is known as dependent variable. 

Simple but important mathematical functions used in equations.


'Log' denotes the natural log and 'Log10' denotes the log to the base 10. Please do not get confuse with analytical commands or commands in scientific calculator. 

Along with the mathematical function, now let's take a look at trigonometric functions. 

Trigonometric functions.

Specific note for trigonometric function is use of angle in degree and radian. 
  1. If you are defining  angle in 'Degree' use sind() as a function, having 'd' as superscript. 
  2. To use inverse trigonometric functions use 'a' as subscript like asind() to get value of angle in degree and asin() to get value of angle in radian. 


Learn best programming practices and be a pro-programmer with simple and easy tips and tricks.

Welcome to my blog!

Dear fellow engineers, w elcome to the bog MATLAB Tips & Tricks. This blog is all about interesting tips and tricks that are useful in MATLAB and Simulink, for quick and efficient programming. Generally experts and coders with more experience use them to get done with codes or mathematical models in Simulink. MATLAB being a mathematical programming environment, it is used by researchers, academicians and industry professionals. Because of the tools which are present in MATLAB, makes it more versatile and useful for wide range of applications.  Rupesh Gosavi started his practice with MATLAB in the year of 2013, during his post-graduation. With this blog he wants to spread the knowledge of MATLAB and Simulink, which he gained over the practice of more then 7 years. He is holding a graduation degree in mechanical engineering and post-graduation in automobile technology. During his post-graduation studies, he found MATLAB being a most interesting, dynamic and research oriented l...

MATLAB Programs - Numerical Methods and Optimization

Roots of Equation - BiSection Method Bisection method is one of the numerical methods to find roots of the equation, included in the syllabus of Third Year Mechanical Engineering course for colleges under University of Pune. The bisection method in mathematics is a root-finding method that repeatedly bisects an interval and then selects a subinterval in which a root must lie for further processing. It is a very simple and robust method, but it is also relatively slow. Because of this, it is often used to obtain a rough approximation to a solution which is then used as a starting point for more rapidly converging methods. Let us consider an example  Figure 1: Polynomial function in f(x)=0 form. To solve polynomial function, it has to be converted into f(x) = 0 form, where all the terms containing powers of x and constant should be on the left-hand side of the equal to sign. Create a function file in MATLAB as shown in figure 1, having a polynomial equation in...
