I have a matrix ex.
A=[11,7,3;9,13,5],
and I want to have a series of variables where
c1=1
c2=7
c3=3
c4=9
c5=13
c6=5.
How can I do an operation like this for any size matrix and note it is important that they are numbered in a certain direction. This is so in a later operation I can input c5 in an equation and it be the value located in A(2,2).

While it is doable; this is almost certainly NOT the way to code whatever it is you have in mind.
Show us the next step of how you intend to use these variables and better solutions will undoubtedly come forth.

it is supposed to be a fast way of having a user input a string of cells in an equation i.e. instead of typing A(1,1)-A(1,2)+A(2,2) etc. it is so it can be quickly inputted by the user once a path is made in the matrix by instead typing c1-c5+c2 etc

You do not need to assign them to variables for this. You can input as a string and analyze the string, pick out the index numbers the user entered and transform them into indices in the original matrix.

I am sorry but I do not know who to do that. That sounds right but I have no idea where to start that
