To solve a system of linear equations you can use Symbolic Math Toolbox. Refer to below Link
https://www.mathworks.com/help/symbolic/solve-a-system-of-linear-equations.html
If you wish to create your own matrix for a given size, you can use zeros function. You can access the individual elements as A(i,j), where i represents number of rows and represents number of columns, as shown below
A = zeros(3,3)
A(1,1) =4
A(1,3) =5
