function create_tridiagonal(n=5, d1=1, d2=2)
output_matrix = zeros(Int64, n, n)
for row in 1:(n-1)
output_matrix[row,row+1] = d2
if row > 1
output_matrix[row,row-1] = d2
end
end
row = n-1
output_matrix[row-1, row] = d2
output_matrix[row+1, row] = d2
output_matrix[diagind(output_matrix)] .= d1
return(output_matrix)
end
Main changes:
Julia
checks matrix size so this is needed if row > 1
row = n-1
-- loops are in local scope, so row
is not saveddiag
function so you need to explicitly say what you want to change diagind(output_matrix)
