unable to input using filename (dxf)

My code: % Reading the dxf-file.

filename = input('Type the name of the dxf-file:');

In command window I write

my_dxf_file.dxf

(saved in the same folder as the file) but get the response:

Error using input Undefined function or variable 'my_dxf_file'

Anyone know why?

Thanks

Ellen, use

 'my_dxf_file.dxf'

with the primes (to make it a string input).

If you want this to be a string, you need to enclose it in single quotest

filename = input('Type the name of the dxf-file:','s');

User enters:

'my_dxf_file.dxf'
