Reverse 2D-lookup table in Simulink

I tried to implement a reverse 2D lookup table in Simulink according to the following description by Fangjun Jiang:
https://de.mathworks.com/matlabcentral/answers/12809-reverse-2d-lookup-table?s_tid=sug_su
First, I wrote the following Matlab code for testing and it does exactly what I expect:
% Absolute eccentricity range
e = 0:1e-06:1.5e-05;
% Piston phase angle range
rad = 0:2*pi/400:2*pi;
% Load capacity matrix
load(‘Tragkraft_alpha_AK_kpl_V03.mat’);
load_cap = Tragkraft_alpha_AK_kpl_V03;
% Instant piston phase angle
rad_dyn = 3.12588469032184;
% Reverse 2D lookup table for load capacity
lookup = interp2(e,rad,load_cap,e,rad_dyn);
% Instant load capacity
load_dyn = 659.331131439451;
% Instant absolute eccentricity
e_dyn = interp1(lookup,e,load_dyn);
After that, I tried to implement it in Simulink using a MATLAB function block with the following code:
function e_dyn = fcn(rad_dyn, load_dyn, load_cap)

% absolute eccentricity range
e = 0:1e-06:1.5e-05;
% piston phase angle range
rad = 0:2*pi/400:2*pi;
% 2D lookup table for load capacity
lookup = interp2(e,rad,load_cap,e,rad_dyn);

% instant absolute eccentricity
e_dyn=interp1(lookup,e,load_dyn);
However, this leads to the following error message that I don’t really understand. In my understanding the Simulink model should do exactly the same as the Matlab code. Can anybody tell me how to fix that in Simulink?I tried to implement a reverse 2D lookup table in Simulink according to the following description by Fangjun Jiang:
