Hi there,
when I generate code from a Simulink model with calibratable vector and matrix parameters, both parameters are generated as 1-dimensional arrays in C code.
Initialization m-file
ADS_InitValue_1x1 = Simulink.Parameter(zeros(1,1));
ADS_InitValue_1x12 = Simulink.Parameter(zeros(1,12));
ADS_InitValue_5x11 = Simulink.Parameter(zeros(5,11));
a2l file (reduced)
/begin CHARACTERISTIC
/* Name */ ADS_InitValue_1x1
/* Type */ VALUE
/end CHARACTERISTIC
/begin CHARACTERISTIC
/* Name */ ADS_InitValue_1x12
/* Type */ VAL_BLK
/* Array Size */
NUMBER 12
/end CHARACTERISTIC
/begin CHARACTERISTIC
/* Name */ ADS_InitValue_5x11
/* Type */ VAL_BLK
/* Array Size */
NUMBER 55
/end CHARACTERISTIC
Unfortunately, with this result it's not possible to distinguish between vector and matrix parameters later in the calibration system.
Is there any possibility to change that behaviour? Or to distinguish between vector/matrix when parsing the a2l file?
Thanks in advance, Thomas

All Simulink signals and parameters will be code generated as 1-D vectors. If all your variable names are consistent with the format you have shown above, you can parse the Name characteristic to extract the NxM portion. If N > 1, the parameter is a matrix.
Another possibility would be to modify the TLC used to generate the a2l file as described in the following documentation: http://www.mathworks.com/help/rtw/ug/customizing-an-asap2-file.html
You would need to modify the asap2scalar.tlc file to include an additional characteristic or comment with the MATLAB parameter dimension.
