Hi there,
i need help trying to implement the kth_polyvec below for the range of temperature values illustrated below. Thank you in advance. kth_polyVec = [ ? ];
%% pre-processing
% thermophysical properties
rho_polyVec = [7939.8, 0.32912];
kth_polyVec = [ ];
Cp_polyVec = [472.2, 0.25];

请先登录，再回答此问题。

Does this work?:
if T >= 1066
kth_polyVec = [14.6, 0.01];
else
kth_polyVec = [50.3, -0.02];
end
