MATLAB读取高光谱数据

只能读取dat类型的高光谱数据

hdr = read_envihdr('d.hdr');
Image = multibandread('d.dat', hdr.size, [hdr.format '=>double'], hdr.header_offset, hdr.interleave, hdr.machine);

Image= reshape(Image,hdr.samples*hdr.lines,hdr.bands);

以下为子函数：

function info = read_envihdr(hdrfile)
% READ_ENVIHDR read and return ENVI image file header information.
%   INFO = READ_ENVIHDR('HDR_FILE') reads the ASCII ENVI-generated image
%   header file and returns all the information in a structure of
%   parameters. 
%
% Output: 
%  * Info - struct with fields provided in the ENVI file. ENVI header 
%             format requires the following fields:
%    * samples - number of samples in the image (columns)
%    * lines - number of lines in the image (rows)
%    * bands - number of bands in the image. If all 3 dimensions are
%      provided than info.size will be created holding 
%      [info.lines info.samples info.bands]
%    * data_type - data type of the image stored as an integer in 1-15 
%      range. If provided than info.format will be created holding string 
%      with Matlab's type name.  
%    * interleave -  file band interleave type; either bip, bsq, or bil are 
%      possible
%    * byte_order - byte order (0 is little endian [least significant
%       byte first], 1 is big endian [most significant byte first]). 
%      If
