| <dl> |
| <dt><em>Description</em>:<dd>Reshapes <var>SOURCE</var> to correspond to <var>SHAPE</var>. If necessary, |
| the new array may be padded with elements from <var>PAD</var> or permuted |
| as defined by <var>ORDER</var>. |
| |
| <br><dt><em>Standard</em>:<dd>Fortran 95 and later |
| |
| <br><dt><em>Class</em>:<dd>Transformational function |
| |
| <br><dt><em>Syntax</em>:<dd><code>RESULT = RESHAPE(SOURCE, SHAPE[, PAD, ORDER])</code> |
| |
| <br><dt><em>Arguments</em>:<dd> |
| <p><table summary=""><tr align="left"><td valign="top" width="15%"><var>SOURCE</var> </td><td valign="top" width="70%">Shall be an array of any type. |
| <br></td></tr><tr align="left"><td valign="top" width="15%"><var>SHAPE</var> </td><td valign="top" width="70%">Shall be of type <code>INTEGER</code> and an |
| array of rank one. Its values must be positive or zero. |
| <br></td></tr><tr align="left"><td valign="top" width="15%"><var>PAD</var> </td><td valign="top" width="70%">(Optional) shall be an array of the same |
| type as <var>SOURCE</var>. |
| <br></td></tr><tr align="left"><td valign="top" width="15%"><var>ORDER</var> </td><td valign="top" width="70%">(Optional) shall be of type <code>INTEGER</code> |
| and an array of the same shape as <var>SHAPE</var>. Its values shall |
| be a permutation of the numbers from 1 to n, where n is the size of |
| <var>SHAPE</var>. If <var>ORDER</var> is absent, the natural ordering shall |
| be assumed. |
| <br></td></tr></table> |
| |
| <br><dt><em>Return value</em>:<dd>The result is an array of shape <var>SHAPE</var> with the same type as |
| <var>SOURCE</var>. |
| |
| <br><dt><em>Example</em>:<dd> |
| <pre class="smallexample"> PROGRAM test_reshape |
| INTEGER, DIMENSION(4) :: x |
| WRITE(*,*) SHAPE(x) ! prints "4" |
| WRITE(*,*) SHAPE(RESHAPE(x, (/2, 2/))) ! prints "2 2" |
| END PROGRAM |
