I need to create a vector B with length = 3;
And i know that B(2) = 5;
Then how to fill B(1) = 0 and B(3) = 0;
Output should be like : B = [0,5,0] ---> CASE 1
EXAMPLE CASE 2:
And i know that B(1) = 5;
Then how to fill B(2) = 0 and B(3) = 0;
Output should be like : B = [5,0,0] ---> CASE 2

Not sure I understand the question, but...
B=zeros(1,3);
%Case 1
B(2)=5
%Case 2
B(1)=5

B = zeros(1,length); B(2) = 5;
//Just initialize the vector with zeros(m,n) function and then feed the data as you want
