| 111 | Parameters |
| 112 | ---------- |
| 113 | shape : int or sequence of ints |
| 114 | Shape of the matrix |
| 115 | dtype : data-type, optional |
| 116 | The desired data-type for the matrix, default is float. |
| 117 | order : {'C', 'F'}, optional |
| 118 | Whether to store the result in C- or Fortran-contiguous order, |
| 119 | default is 'C'. |
| 120 | |
| 121 | Returns |
| 122 | ------- |
| 123 | out : matrix |
| 124 | Zero matrix of given shape, dtype, and order. |
| 125 | |
| 126 | See Also |
| 127 | -------- |
| 128 | numpy.zeros : Equivalent array function. |
| 129 | matlib.ones : Return a matrix of ones. |
| 130 | |
| 131 | Notes |
| 132 | ----- |
| 133 | If `shape` has length one i.e. ``(N,)``, or is a scalar ``N``, |
| 134 | `out` becomes a single row matrix of shape ``(1,N)``. |
| 135 | |
