Matlab实用化小函数(1)--将矩阵数据输出的txt格式的文本文档

%%%%%%%%%%%%%%%%%%%%%%%%需求描述%%%%%%%%%%%%%%%%%%%%%%%%
%将一个数组转化输出为txt格式文档
%%%%%%%%%%%%%%%%%%%%%%%%参数描述%%%%%%%%%%%%%%%%%%%%%%%%
%outputFileName       带输出文本文档名称
%mat                  待输出矩阵
%dataType             待输出矩阵的数据类型
%%%%%%%%%%%%%%%%%%%%%%%%需求实现%%%%%%%%%%%%%%%%%%%%%%%%
function mat2txt(outputFileName, mat, dataType)
fid = fopen(outputFileName, 'w'); %打开文件
[row, col] = size(mat); %获取矩阵的宽度和高度

%循环遍历矩阵各行各列
for i = 1:1:row
    for j = 1:1:col
        if j == col
            fprintf(fid, strcat(dataType, '\r\n'), mat(i,j));%在每一行的尾部输出换行符
        else
            fprintf(fid, strcat(dataType, '\t'), mat(i,j));%在每个元素的尾部输出制表符
        end
    end
end
fclose(fid);%关闭文件
end

%%%%%%%%%%%%%%%%%%%%%%%%调用示例%%%%%%%%%%%%%%%%%%%%%%%%

mat2txt('filename.txt', matrix,  '%d')
