Evaluating a polynomial matrix

New to Julia

Hello,
I’m trying to evaluate a polynomial matrix given by sol[5] in my code at certain values of x and y which I generated using LinRange. I tried to do it, but I’m getting the indices of sol[5] rather that the value of the matrix at any pair (x,y). Here is my code:

x = LinRange(0, 10, 20)
y = LinRange(0, 10, 20)

polynomial_matrix = sol[5]
for i in 1:length(x)
for j in 1:length(y)
xi = x[i]
yj = y[j]
polynomial=polynomial_matrix[xi,yj]

end
end

Perhaps you meant polynomial_matrix[xi, yj]. BTW, try to use Markdown to properly format the code in your post.
