MATLAB Online에서 열기 You don't need table2array. Your example data don't seem to match either description, so I'm just guess what they look like. Also you don't say what kind of plot. >> type = [1;1;1;1;1;2;2;2;2;2;3;3;3;3;3]; ...
conna=database('SampleDB','',''); exec(conna,['create table Table(name string,age int)']); close(conna); Table——表名 name,age——字段名 以上部分是从董振海写的《精通MATLAB7编程与数据库应用》中根据我使用database toolbox的经验摘抄的,在此向作者致谢。 第三部分:自己写的相关函数 下面是...
Create a table. Load arrays of data from the samplepatients.matfile. Then create a table from these arrays using thetablefunction. The names of the input arrays become the names of the table variables. Row names are optional. To specify row names, use theRowNamesname-value argument. Get l...

在MATLAB的GUIDE图形编辑界面中,若需添加一个37行1列的表格(uitable),首先需要在函数文件中定义一个37*1的零矩阵或空矩阵,例如命名为aaa。具体而言,可以在CreatFunction函数中添加如下代码:aaa = zeros(37,1);接着,利用set函数将uitable组件与矩阵关联,通过指定uitable的句柄及设置其Data属性来 ...
