Hi I hope you all doing well, I have an equation (G(A)=g(A,r)*L(r)) wish I want to solve in matrix form by turning the function "g(A,r)" into a matrix where "r" varies by column and "A" varies by row, and in the end I want to plot L(r) but I dont know how to construct this matrix, If any of you have an idea It will help me a lot, Thank you all in advance
Something like this maybe?
Table[G[A, r], {A, 2}, {r, 4}]
I don't know what the ranges should be. 2 & 4 were just arbitrary.
