Such problems are discussed exahustively in the documentation. Please read at least the "Getting Started" chapters, because it is impossible to work with such a powerful language as Matlab without reading the manuals. It is not efficient to discuss such basic questions in the forum, when MathWorks spend so much time and knowhow to create this marvelous and exhaustive documentation already in written form.
