matlab: convert char array into string

Question

I implemented a bash script in matlab, which returns a char array with all the outputs (echo). Now I would like to use the data stored in the array, to open a file. Unfortunately, I don't know how to convert the array into a string. The following code works:

[status, output] = system('./script.sh', '-echo');
filename = [ output(1) output(2) output(3) output(4) output(5) output (6) ];

But it is not very convenient and doesn't allow different lengths of the filename. Is there an easy way to solve this?

does filename = output(:) help? Otherwise can you post the result if you type output in the command line? — Dan

Basically, character arrays are strings; there's no need to convert them.

filename = output

should do the trick.

Okay, my fault...the array had an empty cell (probably a command) at the end, so Matlab couldn't open the file. filename = output(1:end-1) solved it. Thanks!
