How to perform the Matlab for pattern recognition

Let the bias be the probability of turning up a head and denoted by the parameter Q.

If we use a coin with the bias specified by Q to conduct a coin flipping process d times, the outcome will be a sequence of heads and tails.

where nH is the number of heads turned up during d trials.

Now using such a simulated coin with Q = ½ to conduct your experiments based on a sequence of outcomes generated by the random generator from computer.

For example, if the number generated by the random generator is less than 1/2, it assigned to be 0;

otherwise, it will be assigned 1.

In order to run the computer project, run the following

(1) d = 100 and n =100 using a simulated coin with Q = ¼ and ½

(2) d = 10 and n =1000 using a simulated coin with Q = ¼ and ½

(3) d = 100 and n = 1000 using a simulated coin with Q = ¼ and ½

(The result of the execution from program will be drawn into histogram on the PowerPoint)

Dear

I try to perform the Matlab programming with certain formula equations for the Pattern Recognition as below (herewith please refer to the PDF file)

However I am not sure my answers are correct or not

Kindly please provide your opinion and suggestion thus I will be able to improve my computing skills

Prayerfully

Matlab Programming Method

(1)

x = randn (100,1);
d = 100; 
n = 100;
if(x<0.25),
toss = 0; %Head
else
toss = 1; %Tail
end
y = randn (100,1);
y(x<0.25) = 1;
hist(y)

x = randn (100,1);
d = 100; 
n = 100;
if(x<0.5),
toss = 0; %Head
else
toss = 1; %Tail
end
y = randn (100,1);
y(x<0.5) = 1;
hist(y)
