The package "amsmath" contains environments for doing this: for example, 
"\begin{pmatrix}...\end{pmatrix}" gives matrices with the usual 
parentheses (..) surrounding the entries. Other environments provide 
different delimiters. 

The number of columns need not be specified. By default, we can have 
at most 10 columns, but this can be changed by setting the counter

Please see the document "amsldoc.dvi" provided with most LaTeX
