How do I create the following matrices using a for loop

Create the following matrices using a for loop:

Matrix 1: 5 3 6 10 9

6 4 7 11 10

7 5 8 12 11

8 6 9 13, 12

9 7 10 14 13

Matrix 2: 1 1/2 1/3 1/4 1/5

1/2 1/3 1/4 1/5 1/6

1/3 1/4 1/5 1/6 1/7

1/4 1/5 1/6 1/7 1/8

1/5 1/6 1/7 1/8 1/9

Please can you explain to me the steps involved in order to do this task.

Thanks in advance

"Please can you explain to me the steps involved in order to do this task."

Sure, that is easy:

1. Do the introductory tutorials: https://www.mathworks.com/help/matlab/getting-started-with-matlab.html
2. Read the documentation for for and colon.
3. Use any other resources, e.g. look at examples online, search this forum, etc.
4. Practice, make mistakes, learn ....

Since the dimensions of each matrix is 5*5,we can easily create the matrices without any for loop.

However ,since we are specified to use for loop here,the code will be overhwhelmingly long becuase we would have to deal with 5*5=25 individual cells of the matrix separately.

However,an interesting point of observation for matrix 1 is that ,each column starts with a partcular number or value and the corresponding values going down the row for that particular column are just incremented by 1.So we can create a 5*5 matrix at first,and then initialize the first row with the respective values as given.Now we can iterate from the second row till the last row,where each cell's value is basically the upper cell's(i.e the cell in the upper row of the same column) value incremented by 1.

So,this might certainly be a pattern finding question which is meant to strengthen your observation skills.

Code snippet for matrix 1:

a=zeros(5,5);
for i=1:1
    for j=1:5
        if(j==1)
            a(i,j)=5;
        end
        if(j==2)
            a(i,j)=3;
        end
        if(j==3)
             a(i,j)=6;
        end
        if(j==4)
             a(i,j)=10;
        end
        if(j==5)
             a(i,j)=9;
        end
    end
end
for i=2:5
    for j=1:5
        a(i,j)=a(i-1,j)+1;
    end
end
