Pass the content of a variable to a .bat file from matlab

Sorry, I have a new problem. I have this char variable: name='file.pdf';

when I do !test name

I see in the file test.bat "name", that is the container of the variabile but not the content of the variable.....I need to pass the content name.pdf to the file test.bat.

How can I resolve?? How cas I pass the string name.pdf to the .bat?

Use system instead for command form to evaluate variables in building the command string. ! ("Bang") interprets everything after it as character string so doesn't (as you've discovered) evaluate the variable before passing it to the OS.

>> f='c*.m';  % selected list of m-files in variable
>> [~,res]=system(['dir /b ' f])  % do a command; "dir" in the example...
res =
categorizeDesignated.m
currenteval.m
>>

ADDENDUM

Just do it again...

system(['report.bat ' res])

Or, more likely you'd want in real life something like

system(['report.bat <dir /b ' f])

Build the string that are going to submit just as you would any other string in Matlab; the limitation is that must(*) use the functional form instead of the bang operator to get a variable interpreted.

() without resort to evil *eval, which route I'm not going to suggest...albeit under some circumstances it is useful.
