I am trying to make a matrix like

` 1n -1 1n 2 1n 1 1n 3 `

The first column is going to be concatenated string where the first alphabet is the counter of the for loop and the alphabet 'n'

For ex: for coun = 1:1:10

`code will go here`

end

should give output for coun = 3 as:

`3n3n3n3n`

and then I need to put this along with a new matrix j which is

`-1213`

The order of the final matrix is decided by the matrix j as it has the same number of rows as the number of rows of the matrix j.

So the final output is:

` 3n -1 3n 2 3n 1 3n 3 `
