[MATLAB混合编程] matlab7.1里m文件转dll

[lancelotdevil]

matlab7.1里用mex -setup后出现;Warning: The file extension of 32-bit Windows MEX-files was changed
from ".dll" to ".mexw32" in MATLAB 7.1 (R14SP3). The generated
MEX-file will not be found by MATLAB versions prior to 7.1.
Use the -output option with the ".dll" file extension to
generate a MEX-file that can be called in previous versions.
