Using unix within MATLAB

I know there are several questions similar to this one, but none seem to be applicable in my scenario.

I want to convert a pdf (or eps) file from my matlab code into a png, using the downloadable software called ImageMagick.

In my command terminal, in order to execute this file format switch, I must type

convert file_name.pdf    new_file_name_with_new_format.png

then, if I wanted to display it, (which I do), I go

display new_file_name_with_new_format.png

This works fine in the terminal window, but how can I do this in matlab? What specific syntax should I use.

I've tried some stuff with !, but to no solution.

Thanks,

Gauss.

oldname = 'file_name.pdf';
newname = 'new_file_name_with_new_format.png'

command = sprintf('convert ''%s'' ''%s''', oldname, newname);
system(command);

command = sprintf('display ''%s''', newname);
system(command)

Thanks for your reply.

I'm getting the problem

/bin/bash: convert: command not found

Could this possible be due to the location in which convert and display are in?

They are stored in

/opt/local/bin/convert

and

/opt/local/bin/display

Do I have to reference this somehow in my matlab code?

Thanks!

command = sprintf('/opt/local/bin/convert ''%s'' ''%s''', oldname, newname);
