I have a cell array named "list" of 900 rows and 9 columns, each element of the cell array contains a string. i want to extract few rows of "list" to create a new cell array. The rows that i need are stored in a vector named "a".

@Miguel Reina: the difference is simple:

{} curly braces refer to the cell contents.
() parentheses refer to the cells themselves.

Because you wanted to get a subset of the cell array, all you need is to use parentheses to refer to the cells themselves. Read more in the MATLAB documentation:
