Generates coordinates of a 2D structured grid by mapping coordinates of a reference grid by the specified scalar functions that map coordinate vectors from the reference domain to individual coordinate components in the actual domain. Target field can be the same as the reference field (in this case coordinates of the reference field are overwritten one by one).Function can be used for transformation of any nodal vector values of a grid, not just for transformation of coordinates.Consistency of dimensions and existence of objects are checked and exceptions are thrown when checks fail.
referenceField | Field containing reference coordinates that will be mapped to actual coordinates. |
Dimensions must be set and array of vector values (coordinates) must be allocated before the function is called.
targetField | Field for which coordinates are generated. |
Dimensions must be set and consistent with dimensions of the reference field, and array of vector values must be allocated before the function is called.
This parameter can be the same field as referenceField .
fx | Function that maps node coordinates of the reference grid to the first node coordinates of the actual grid. |
fy | Function that maps node coordinates of the reference grid to the second node coordinates of the actual grid. |

Returns element of the field at specified indices.
i1 | The first index of an element in a 2D array (least significant). |
i2 | The second index of an element in a 2D array. |
Indexing of elements of the structured 2D field has changed in 2011. Now the first index (in x direction) is least significant and the last one is most significant, opposite to notation in matrices. $A Igor Jan08 Oct11;
