MatrixForm

MatrixForm[list]

prints with the elements of list arranged in a regular array.

Details and Options

  • In StandardForm the array is shown enclosed in parentheses.
  • MatrixForm prints a singlelevel list in a column. It prints a twolevel list in standard matrix form. More deeply nested lists are by default printed with successive dimensions alternating between rows and columns.
  • Elements in each column are by default centered.
  • MatrixForm prints SparseArray objects like the corresponding ordinary lists. »
  • MatrixForm takes the same set of options as TableForm.
  • MatrixForm acts as a "wrapper", which affects printing, but not evaluation.
