Hi dear Matlab community,
I have a question concerning the import of a .mat - file which contains variables of the same name. When I try to import the file, only one array will be imported because it has the same name as the following ones (see picture below). Is there a way to import all of the arrays and give them different names while importing?
Thanks for your help,
David

David - I didn't realize it was possible to save a variable with the same name more than once to a mat file. Are you sure that all these variables have the same name, or does the above just show the truncated names of the variables (due to space limitation)? It would be interesting to know the code that you were using that allowed you to do this.

Yeah I was also wondering. Actually I can´t give you any code because a program converted a CAN - Measuring to this .mat format. And yes all these variables have got the same names for sure. Any idea how I could load this whole .mat file into MATLAB?

Did you create the mat file with the -append option? From the help for save():
save(filename,variables,'-append') adds new variables to an existing file, and does not overwrite it.
Perhaps that is how you got multiple copies of the variable in there.

It shows the same as on the right column in the workspace. I have only on variable for each value but not multiple ones.

Then where did you get that screenshot that showed that there were multiple versions of the variable?
