matlab将.mat数据文件转换成.dat/.txt数据文件

//把矩阵 matrix 保存成任意后缀的文件

//转换成 .txt 举例：mat2txt( ‘filename.txt’, data );

//转换成 .corr 举例：mat2txt( ‘filename.corr’,data );

转换成 .dat 举例：mat2txt( ‘filename.dat’, data );

function back = mat2txt( file_Name, matrix )

fop = fopen( file_Name, ‘wt’ );

[M,N] = size(matrix);

for m = 1:M

for n = 1:N

fprintf( fop, ’ %s’, mat2str( matrix(m,n) ) );

end

fprintf(fop, ‘\n’ );

end

back = fclose( fop ) ;

例如：将data.mat转化为data.dat

fop = fopen( ‘保存路径\data.dat‘, ‘wt’ ); %创建一个新文件

[M,N] = size(data);

for m = 1:M

for n = 1:N

fprintf( fop, ’ %s’, mat2str( data(m,n) ) );

end

fprintf(fop, ‘\n’ );

end

back = fclose( fop ) ;
