MID-TERM ASSIGNMENTQuestion :If an experiment will either succeed (成功) or fail (失敗). The probability of success is 30%, therefore, that of failure is 70%. To record the result of experiment, let 1 represents the success, and 0 represents the failure. In fact, this is so-called Bernoulli distribution (伯努力分配). How to create a random scalar, who has 30% of probability to be 1, while 70% of probability to be 0? In practice, we can make a random uniform distribution scalar (denoted by y, 0Please make a random matrix (size=100×50) consisting of independent Bernoulli distribution (for any element of the matrix, it can be either 1 or 0, according to the probability of 30% and 70%, respectively)Answer :Method 1Method 2vs=rndu(100,50);result=zeros(100,50);for i(1,100,1);    for j(1,50,1);       if vs[i,j]>0.3;        result[i,j]=0;       else;        result[i,j]=1;       endif;    endfor;endfor;result;vs=rndu(100,50);result=zeros(100,50);for i(1,100,1);    for j(1,50,1);       if vs[i,j]<0.3;        result[i,j]=1;       else;        result[i,j]=0;       endif;    endfor;endfor;result;Explanation :Method 1vs=rndu(100,50); //I want to create random uniform consist of 100 rows and 50 columns// result=zeros(100,50); //I want to fill the random uniform with zeros of 100 rows and 50 columns//for i(1,100,1); //i represent the row. I want the rows start with 1 end in 100 with 1 interval//    for j(1,50,1); //j represent the column. I want the column start with 1 end in 50 with 1 interval//       if vs[i,j]>0.3;//to make command for the content of random uniform that I made, if greater than 0.3 means fail represent by 0//        result[i,j]=0;//the result of the command that was made. 0=fail//       else;//for other result//        result[i,j]=1;//other than the above command or less than 0.3 means success represent by 1//       endif; //to close the command//    endfor;//to close the command//endfor;//to close the command//result;//to pull out the result//[pic 1]Method 2vs=rndu(100,50); //I want to create random uniform consist of 100 rows and 50 columns//result=zeros(100,50); //I want to fill the random uniform with zeros of 100 rows and 50 columns//for i(1,100,1); //i represent the row.
