Why does code generator transform matrix to array?

Hi all,

I have a matrix (lets say of dimension 2x3), that is used in an interp1-function in my Simulink model. This interpolation interpolates only one dimension of the matrix, so the result is of dimension 3. Which is correct so far.

Generating c code (ert target) makes the matrix of dimension 2x3 an array of dimension 6. The result of the calculation in the code is still correct, by I need the matrix still to be a matrix (for calibration purpose).

Anyone an idea why the matrix is transformed to an array and how I can avoid this?

Thanks for your help.

Not an answer to my question, but a work around if anyone has a similar problem: instead of using the interp1 function I now use a Lookup Table. Here I can set the matrix as the table data. Nevertheless in the code it's still an array, but at least it's defined as a matrix in the a2l file now.
