用Matlab的File/import Data
将1.txt数据文件导入以后,怎么load?格式是什么?急阿!
GzLi (笑梨) 于Tue Dec 3 11:04:52 2002提到:
1.txt
ascii数据
比如
1 2 3 3
2 2 2 2
2 3 3 3
可以用
mydata=load('1.txt')

matlab中有一个专门的两行的程序,很简单,可惜记不清了

help load
LOAD Load workspace variables from disk.
LOAD FILENAME retrieves all variables from a file given a full pathname
or a MATLABPATH relative partial pathname (see PARTIALPATH). If FILENAME
has no extension LOAD looks for FILENAME and FILENAME.mat and treats it
as a binary "MAT-file". If FILENAME has an extension other than .mat, it
is treated as ASCII.
LOAD, by itself, uses the binary "MAT-file" named 'matlab.mat'. It is
an error if 'matlab.mat' is not found.
LOAD FILENAME X loads only X.
LOAD FILENAME X Y Z ... loads just the specified variables. The
wildcard '*' loads variables that match a pattern (MAT-file only).
LOAD -ASCII FILENAME or LOAD -MAT FILENAME forces LOAD to treat the file
as either an ASCII file or a MAT file regardless of file extension. With
-ASCII, LOAD will error if the file is not numeric text. With -MAT, LOAD
will error if the file is not a MAT file generated by SAVE -MAT.
If FILENAME is a MAT file, requested variables from FILENAME are created
in the workspace. If FILENAME is not a MAT file, a double precision array
is created with name based on FILENAME. Leading underscores or digits in
FILENAME are replaced with X. Other non-alpha chars in FILENAME are
replaced with underscores.
S = LOAD(...) returns the contents of FILENAME in variable S. If
FILENAME is a MAT file, S is a struct containing fields matching the
variables retrieved. If FILENAME is an ASCII file, S is a double
precision array.
Use the functional form of LOAD, such as LOAD('filename'), when the
file name is stored in a string, when an output argument is requested,
or if FILENAME contains spaces.
See also SAVE, WHOS, UILOAD, SPCONVERT, PARTIALPATH, IOFUN, FILEFORMATS.

load函数应该与save函数相对吧,前两天用save想将一整型数组保存
在文档中,但是无论怎样选择参数,保存的始终是浮点数,哪位能指
点一下怎样用save保存整型数组(abc.txt打开后是整数而不是浮点数)?

1.fwrite 控制参数
2. 在workspace中显示,然后copy - paste
都是极笨的办法,我没有找到其它方法。
