LCONTOUR contour a scalar on a FEM grid. |
|---|
| 12 |
LCONTOUR contours a scalar field on the input FEM grid. |
|---|
| 13 |
LCONTOUR accepts a vector of values to be contoured |
|---|
| 14 |
over the provided mesh. |
|---|
| 15 |
|
|---|
| 16 |
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>) |
|---|
| 17 |
Q - scalar to be contoured upon; must be a 1-D vector |
|---|
| 18 |
or the single character 'z', IN SINGLE QUOTES!! |
|---|
| 19 |
cval - vector of values to contour |
|---|
| 20 |
|
|---|
| 21 |
In order to contour the FEM domain bathymetry, pass |
|---|
| 22 |
in the string 'z' in place of an actual scalar field Q. |
|---|
| 23 |
You could, of course, pass in the actual bathymetry as |
|---|
| 24 |
the scalar to contour. Otherwise, Q must be a 1-D vector |
|---|
| 25 |
with length equal to the number of nodes in the FEM mesh. |
|---|
| 26 |
|
|---|
| 27 |
The parameter/value pairs currently allowed in the LCONTOUR |
|---|
| 28 |
function are as follows (default values appear in {}) : |
|---|
| 29 |
|
|---|
| 30 |
Color {'r' = red} |
|---|
| 31 |
LineStyle {'-' = solid} |
|---|
| 32 |
LineWidth {0.5 points; 1 point = 1/72 inches} |
|---|
| 33 |
MarkerSize {6 points} |
|---|
| 34 |
|
|---|
| 35 |
See the Matlab Reference Guide entry on the LINE command for |
|---|
| 36 |
a complete description of parameter/value pair specification. |
|---|

The idea and some of the constructs used in pv decoding |
|---|
| 39 |
in this routine come from an unreleased MathWorks function |
|---|
| 40 |
called polar2.m written by John L. Galenski III |
|---|
| 41 |
and provided by Jeff Faneuff. |

OUTPUT : h - the handle to the contour line(s) drawn |
|---|
| 44 |
|
|---|
| 45 |
CALL : >> h=lcontour(<A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A>,Q,cval,p1,v1,p2,v2,...) |
|---|
| 46 |
or |
|---|
| 47 |
>> h=lcontour(<A HREF = "../3.FEM/fem_grid_struct.html">fem_grid_struct</A>,'z',cval,p1,v1,p2,v2,...) |
