Application of Monte Carlo Method Based on Matlab: Calculation of Definite Integrals and Simulation of Heston's Model Yannan Gao

Email: sddxgyn@qq.com. 2 School of management, Shandong Womens University, Daxue Road No. 2399, Changqing District, Jinan, Shandong, China. Email: 965509529@qq.com Abstract. This paper discusses Monte Carlo method in three aspects: pi-approximation, an
algorithm to calculate definite integral and simulation to generate financial time series. The first two calculations are based on geometric probability: to calculate the probability that the random points fall within the certain area. The third one is to transfer a stochastic differential equation into a difference equation and realize these equations on matlab to derive a time series which has the properties of the corresponding stochastic differential equation. By analyzing these time series, one can make further analysis on these data, e.g. density function. The paper shows the applicability of Monte Carlo method. The method gives practitioners accessible means of solving complicated models and is easy to operate on computers. One uses Monte Carlo method to get statistical conclusions by applying simulation techniques to carry
on numerous experiments on computers. The method can simplify some complicated mathematical sciences, statistics and finance. An example is that a finance guy can simulate return time series of
financial assets and do further research on that data. Mathematicians can solve difficult equations or
make numerical calculations through this simple but tricky method. This paper tries to illustrate the
charm of this method and provides some codes based on the software matlab, which could be a good reference for the readers to get captivated by this interesting method. 1. Calculating Pi Using Monte Carlo Method
Calculating pi by using simulation method is a computer realization of the so-called random
experiment in statistics. There are many ideas supporting this realization. A common one is that one can calculate the ratio of the areas between a square with the side length 1 and its inscribed circle.
Referring to the geometric probability, one throws many beans, (the size of which is so small that it
can be ignored) into a square sided 1.The probability that the beans fall within the inscribed circle is
easy to derive that k is equal to ʌC4. The more concrete idea of the algorithm is to generate two random numbers x and y which follow uniform distribution at the interval (-1, 1). Each time when matlab generates a pair of numbers x and y,
we form a coordinate which corresponds to a point within the square. The equation of inscribed circle
is x 2+y 2 =1. The points in the circle must satisfy the condition x 2 +y 2 <1. The codes are presented as in appendix B. N denotes the number of times of throwing beans. m is used to keep record of the number of beans 21234567890 '"""

random numbers are newly generated every time matlab calculates a result. One can write a code including a function using the command function in matlab so that one can call the program to
calculate pi. Another thing to mention is that one can take average of different results generated by
same n. From Table 1 we can find that the calculating result is different. And the bigger n is, the more

2. Calculating Definite Integral Using Monte Carlo Simulation Method
The idea of the calculation of definite integral is very similar. According to the geometric meaning of
definite integral, definite integral is the area of the geometric figure that integrand curve and horizontal
axis form at a definite integral. Therefore, we can transfer the ratio into the definite integral according
