INTERP_SCALAR - interpolate scalar values onto scatter points |
|---|
| 12 |
INTERP_SCALAR Interpolates a scalar defined at all 2-D grid points |
|---|
| 13 |
in the <A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A> onto the scattered points (x,y). |
|---|
| 14 |
|
|---|
| 15 |
INPUT : <A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A> (from <A HREF = "../3.FEM/loadgrid.html">LOADGRID</A>, see <A HREF = "../3.FEM/fem_grid_struct.html">FEM_GRID_STRUCT</A>) |
|---|
| 16 |
q - scalar field to interpolate |
|---|
| 17 |
x,y - points to interpolate to (optional) |
|---|
| 18 |
j - elements that contain x,y points (optional) |
|---|
| 19 |
|
|---|
| 20 |
If x,y are not passed in, INTERP_SCALAR prompts the user |
|---|
| 21 |
to specify a location with the mouse. In this case, |
|---|
| 22 |
the location, element number, and interpolated vaule |
|---|
| 23 |
are returned through the first output argument, or else |
|---|
| 24 |
to the screen, as [x y j outq]. |
|---|
| 25 |
|
|---|
| 26 |
If j is not passed in, INTERP_SCALAR locates the points |
|---|
| 27 |
within <A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A> and returns the element list |
|---|
| 28 |
if two output arguments are provided. |
|---|
| 29 |
|
|---|
| 30 |
OUTPUT : outq - interpolated values |
|---|
| 31 |
j - elements (optional) |
|---|
| 32 |
x,y - mouse-specified point (optional) |
|---|
| 33 |
|
|---|
| 34 |
CALL : outq=interp_scalar(<A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A>,q); (mouse-driven) |
|---|
| 35 |
[outq,j]=interp_scalar(<A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A>,q,x,y); |
|---|
| 36 |
outq=interp_scalar(<A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A>,q,x,y,j); |
