converting cell to str

Hi.

I am trying to load a bunch of log files, and then find certain keywords in it.

C is the cell containing the 40 input files in which i want to find certain keywords.

iscellstr(C) = 0

Since i cannot use C in strfnd, i have to convert it into C2 as:

C2 = [C{:,i}]

However, here's the main problem. C contains all the 40 files i want to read, but C2 contains only one, the 40th file.

Any suggestions about the conversion will be appreciated.

Thanks in advance,

Mahesh
