# rec2XY

Returns the X and Y coordinates corresponding to specified record numbers in a georeferenced grid.

### Calling Sequence

    XY = rec2XY ( Header , C )

### Arguments

Header

  Vector of 7 elements describing the grid georeferencing (as returned by `GetFloatRasterHeader` or `GetFlowDirGridHeader`) : number of columns, number of lines, cellsize, X coordinate of lower-left pixel, Y coordinate of lower-left pixel, NODATA value, convention for positioning the lower-left pixel.

C

  Matrix containing the record numbers in the grid, to be converted in XY coordinates.

XY

  Output : vector of size `[length(C),2]`, coordinates of the specified record numbers.

### Description

Returns the X and Y coordinates corresponding to specified record numbers in a georeferenced grid.

The point with coordinates `(x_i,y_i)` is associated with pixel `(row_i,col_i)` in the grid, i.e. record `rec_i = row_i * ncols + col_i`
