100个matlab学习程序，通过它可以全面的学会matlab编程，和一些简单算法的使用(100 matlab learning process, it can fully learn matlab programming, and some simple algorithm using )

C-mex files for MATLAB encounter the following problem when compiling them with WATCOM 11.0: All access-functions to files (fprintf, fscanf) cannot handle double variables, only integer and strings are read or written correctly. The file convert.c contains two functions: You may read a double-variable as a string from the file and convert it to a double (function string2double) and you may convert a double to a string (function double2string) and write it to a file (see main() in convert.c). The file conditio.dat is an example of numbers read by convert.c. The conv.exe was compiled on a Windows95-system. The files were tested for MATLAB 5.2 and WATCOM 11.0a result of "ver" is: MATLAB Version 5.2.1.1420 on PCWIN (C-mex files for MATLAB encounter the following problem when compiling them with WATCOM 11.0: All access-functions to files (fprintf, fscanf) cannot handle double variables, only integer and strings are read or written correctly.
