MATLAB: About reading MDF files

mdfmdfimport

I would like to use MATLAB to read commonly used MDF files for automobiles.

Currently, MDF 3.0 can be read by mdfimport.m, but MDF files of MDF 3.0 or later can not be read.

Can't read MDF files without using vehicle network toolbox?

https://pypi.org/project/mdfreader/ is a python project that can read MDF 4 files. It can be invoked from MATLAB.

The error you are encountering often occurs when the MDF file is not sorted. By applying a data sort to the file, it becomes readable.

You can use “mdfSort” function to sort the file and make the file readable.

mdfSort ('oldFile.mdf', 'newFile.mdf');
mdfObj = mdf('newFile.mdf');
data = read(mdfObj);

MATLAB: TLC – Get the reference to the PWork vector in r2018a

Dear Glen,

It seems Mathworks has changed the API access for CGType massively since R2017b. The new API to query the CGType.Member.Name is LibCGTypeMemberName(cgTypeIdx, memberIdx) found in the following file.

MATLABROOT/rtw/c/tlc/lib/dtypelib.tlc:849:%% Function: LibCGTypeMemberName ===========================================
MATLABROOT/rtw/c/tlc/lib/dtypelib.tlc-850-%% Abstract:
MATLABROOT/rtw/c/tlc/lib/dtypelib.tlc-851-%%   Returns the name of a member of a struct CGType
MATLABROOT/rtw/c/tlc/lib/dtypelib.tlc-852-%%
MATLABROOT/rtw/c/tlc/lib/dtypelib.tlc:853:%function LibCGTypeMemberName(cgTypeIdx, memberIdx) void

I am not sure if you are still looking for a solution to this question. But, I believe it is one of the only questions relevant to the recent change in the CGType APIs that I found on the Google searches and yet unanswered.

I would suggest finding the rest of the changed APIs by grep-ing through the installed TLC files in R2018a.

Hope this helps!

Siraj
