How to specify a path in matlab code?

Sir/Madam I have to use log_barrier and l1eq_pd functions from L1-magic toolbox for my Compressed Sensing project. While giving path name its showing error as:

Directory access failure: \D:\anusha\FINAL_PROJECT\FACS_Ver1.1\L1_magic\l1magic\Optimization.

and

??? Undefined function or method 'l1eq_pd' for input arguments of type 'double'.

Please tell me how to solve this problem.

It almost sounds like your are missing the function l1eq_pd which is typically what this error implies. From the command line type:

help l1eq_pd

What is returned? Is there a description for this function? If not, then the function is missing.

Use pathtool to edit the MATLAB path to include

D:\anusha\FINAL_PROJECT\FACS_Ver1.1\L1_magic\l1magic\Optimization

with no "\" at the beginning of it.

And of course re-check that the directory is the one where the code has been placed.
