Issue with Lookup Table Code Generation?

Hello,

I'm trying to generate code from the Embedded Coder. I have a couple of lookup tables in my model but it appears they are not converted well from the model to the C code.

Do I have to set some specific parameters or flag some particular option?

Thanks!

Column-Major Layout to Row-Major Layout Conversion of Models with Lookup Table Blocks

Ok, thanks. My LUT is a 1-D one. Does the conversione benefit from the column-major to row-major also in this case?

No. What is your issue?

[Matteo Manzini]

I have a very simple LUT for a linear conversion. More or less 15 points for breakpoints and table data but apparently I don't get the exact interpolation once I have converted the model to code. I basically get only a couple of outputs from the LUT, it seems like the interpolation is not working.

You can run your simulation in normal mode and SIL mode (software in the loop, which is C code) and compare.
