非下采样Contourlet分解

Question

我有一张图片（医学影像）1024 * 1024我正在尝试使用NSCT工具箱对其进行分解，但每次运行代码时都会出现此错误：

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

我正在使用的唯一mex文件是工具箱中的文件

http://www.mathworks.com/matlabcentral/fileexchange/10049-nonsubsampled-contourlet-toolbox

nlevels = [0, 1, 3] ;        % Decomposition level
pfilter = 'maxflat' ;              % Pyramidal filter
dfilter = 'dmaxflat7' ;              % Directional filter

% Nonsubsampled Contourlet decomposition
coeffs = nsctdec( double(im), nlevels, dfilter, pfilter );

Answer 1

我收到此错误，因为mex文件不正确，我的系统是windows7 64位mex文件是.mexmac
