How to update lookup table during simulation? Simulink

Hello,

I have vector X (length), Y (width) and matix Z (locals high), which desciber road for car simulation. For locals high Z I use lookup table and bearkpoints 1 is X and bearkpoints 2 is Y. Center of mass for car is describer by (x, y, z). I want to add some value in each step of simulation to Z matrix after car is pasing lokal z. How to update data in lookup table?

Best regards

Marcin

Hi there,

I assume that you want to update the breakpoint data, right? Simulink generally supports dynamic lookup tables, i.e. tables where you provide the breakpoint data as inputs: Approximate a one-dimensional function using dynamic table - Simulink - MathWorks Deutschland

Depending on your problem, it may however be easier to implement the loopup method directly yourself in Simulink or use a call to Matlab via the Matlab Function block (Include MATLAB code in models that generate embeddable C code - Simulink - MathWorks Deutschland) or S-Functions, where you can specify the breakpoint data as input.

Thus, you would have to check what is most suited and efficient for your problem.
