PLOTDROG plot drogue .pth file output from DROG3D or DROG3DDT. |
|---|
| 12 |
PLOTDROG plots the paths of drogue locations as specified |
|---|
| 13 |
in the x,y coordinate arrays. PLOTDROG takes as required |
|---|
| 14 |
arguments the x,y coordinates of the drogue locations AND |
|---|
| 15 |
the number of drogues in the path file. The path information |
|---|
| 16 |
from DROG3D or DROG3DDT can be read into MATLAB with |
|---|
| 17 |
READ_PTH, which reads .pth files. |
|---|
| 18 |
|
|---|
| 19 |
PLOTDROG draws each drogue with a separate line, solid |
|---|
| 20 |
by default. Each drogue line is referenced with |
|---|
| 21 |
one object handle. Therefore, to change the linetype or |
|---|
| 22 |
color of the lines, use the MATLAB command SET and the handle |
|---|
| 23 |
returned by PLOTDROG. |
|---|
| 24 |
|
|---|
| 25 |
Even though READ_PTH returns the entire path matrix, only |
|---|
| 26 |
two columns of it are passed to PLOTDROG. It is up to the |
|---|
| 27 |
user to make sure the correct ones are passed in. I.e., |
|---|
| 28 |
there is no way for PLOTDROG to ensure x,y represent |
|---|
| 29 |
HORIZONTAL coordinates, etc. |
|---|
| 30 |
|
|---|
| 31 |
INPUT: |
|---|
| 32 |
x,y - x,y coordinates of drogues |
|---|
| 33 |
ndrog - number of drogues in path matrix; |
|---|
| 34 |
this number is returned by READ_PTH |
|---|
| 35 |
tstride - time stride (optional, def = 1) is |
|---|
| 36 |
the number of timesteps to skip over. 1 would |
|---|
| 37 |
mean "plot all timesteps"; 2 would mean "plot |
|---|
| 38 |
every other timestep"; i.e., skip every other |
|---|
| 39 |
timestep; etc... |
|---|
| 40 |
dstride - drogue stride (optional, def = 1) is |
|---|
| 41 |
the number of drogues to skip; see tstride above. |
|---|
| 42 |
In order to specify dstride, you must also specify |
|---|
| 43 |
tstride. |
|---|
| 44 |
|
|---|
| 45 |
Both tstride and dstride can be vectors of specific timesteps |
|---|
| 46 |
or drogue numbers to plot. In order to plot only ONE drogue |
|---|
| 47 |
or ONE timestep, pass into PLOTDROG the values of tstride |
|---|
| 48 |
and/or dstride enclosed in {}'s. For example, to |
|---|
| 49 |
plot the initial drogue locations, call PLOTDROG as: |
|---|
| 50 |
>> h=plotdrog(x,y,ndrog,{1}); |
|---|
| 51 |
To plot the 3rd drogue for all timesteps, call PLOTDROG as: |
|---|
| 52 |
>> h=plotdrog(x,y,ndrog,1,{3}); |
|---|
| 53 |
|
|---|
| 54 |
OUTPUT: |
|---|
| 55 |
h - the handle(s) to the path lines on the current axes |
|---|
| 56 |
|
|---|
| 57 |
dstride - the number of drogues to skip, see tstride above. |
|---|
| 58 |
In order to specify dstride, you must also specify |
|---|
| 59 |
tstride. |
|---|
| 60 |
|
|---|
| 61 |
CALL: h=plotdrog(x,y,ndrog); |
|---|
| 62 |
h=plotdrog(x,y,ndrog,tstride); |
|---|
| 63 |
h=plotdrog(x,y,ndrog,tstride,dstride); |
