READ_S3C read a FEM output file of <A HREF = "../4.IO_Functions/s3c.html">s3c</A> filetype. |

READ_S3C is part of a suite of OPNML I/O functions |
|---|
| 16 |
to read specific filetypes pertaining to FEM model |
|---|
| 17 |
input and output. These functions allow the user to |
|---|
| 18 |
get these data files into MATLAB without copying the |
|---|
| 19 |
files and removing the header info by hand. |
|---|
| 20 |
|
|---|
| 21 |
READ_S3C reads the FEM filetype <A HREF = "../4.IO_Functions/s3c.html">s3c</A>, as |
|---|
| 22 |
detailed in "Data File Standards for the Gulf of Maine |
|---|
| 23 |
Project" from the Numerical Methods Laboratory at |
|---|
| 24 |
Dartmouth College. (This document is located in the OPNML |
|---|
| 25 |
notebook under External Documents.) There are four |
|---|
| 26 |
columns, the first of which is the node number. The |
|---|
| 27 |
remaining columns are floating point. |
|---|
| 28 |
|
|---|
| 29 |
Input : If fname is omitted, READ_S3C enables a file browser |
|---|
| 30 |
with which the user can specify the .<A HREF = "../4.IO_Functions/s3c.html">s3c</A> file. |
|---|
| 31 |
|
|---|
| 32 |
Otherwise, fname is the name of the <A HREF = "../4.IO_Functions/s3c.html">s3c</A> file, relative |
|---|
| 33 |
or absolute (fullpath), including the suffix '<A HREF = "../4.IO_Functions/s3c.html">s3c</A>'. |
|---|
| 34 |
This input is a string so it must be enclosed in single |
|---|
| 35 |
quotes. The header lines are discarded. |
|---|
| 36 |
Output : The data part is returned in the variable data. |
|---|
| 37 |
|
|---|
| 38 |
Call READ_S3C as: |
|---|
| 39 |
>> [data,freq,nnv]=read_s3c(fname); |
|---|
| 40 |
<A HREF = "../4.IO_Functions/s3c.html">s3c</A> filetypes contain both the frequency and the number |
|---|
| 41 |
of vertical nodes as header info, which will be returned |
|---|
| 42 |
to the user. |
|---|
| 43 |
|
|---|
| 44 |
If READ_S3C cannot locate the file, it exits, returning |
|---|
| 45 |
a -1 instead of the data matrix. |
|---|
| 46 |
|
|---|
| 47 |
NOTES : The .<A HREF = "../4.IO_Functions/s3c.html">s3c</A> filetype contains 3-D data; i.e., complex-valued |
|---|
| 48 |
scalar data at each vertical node per horizontal node. |
|---|
| 49 |
|
|---|
| 50 |
Call as: [data,freq,nnv]=read_s3c(fname); |
