x = [task_queue[i] > 0 && i<NUM_FLOOR]{i++;}/{a =1;};

Although you can do it with regexp, why would you? strfind will do the job here. What do you want to do with the result?

You were close: you forgot to make the expression lazy, and you forgot you included the close bracket from the sting when excluding the / matched part.
str='x = [task_queue[i] > 0 && i<NUM_FLOOR]{i++;}/{a =1;};';
a=regexp(str,'[^/]({.*?})','tokens');
a{1}

Thanks alot rik :)
i did a small correction to the expression
str='x = [task_queue[i] > 0 && i<NUM_FLOOR]{i++;}/{a =1;};';
a=regexp(str,'(?<!/\s*){.*?}','match');
a{1}
just to make sure the before letter is not followed by /.
