Hi,everyone!

I have met a problem when ran a M program.

For example,running the program will product a variable as 'a_1'.And the number '1' is random.

Now,I want to get the value of 'a_number' and apply to myself M program.

How to do?

Thanks.

If I need to deal with different signals,using mdfimport will product many variables . Is there a better way?

@MT_jsmith: if you are using this FEX submission, then no, there is no better way because unfortunately the author made some bad design decisions, and instead of simply returning a structure they make all of the variables magically appear in the workspace. Basically their bad design decision forces you to write bad code.

However there is a simple solution: download this much better designed tool:

which lets you simply load into an output variable (a cell array):

data = importMDF3(...)

Note that the MATLAB Vehicle Network toolbox also supports reading MDF files:
