% Using inputdlg() to obtain information and save it to cell array data(1:5, 1:4) = repmat(inputdlg(prompt,title,[1, 50],definput)', 5, 1); 这里用到了MATLAB自带的inputdlg函数,其作用是打开一个收集用户输入的对话框,并将输入的信息赋给一个变量(在这里就是赋给我们刚刚创建的cell矩阵啦...
此时变量区还没simin变量,所以还是个红色提示状态。 该模块导入数据的方式有三种:timeseries, matrix, structure,下边是其主要参数介绍 Data:用于设置变量名为 simin Output data type:用于设置输出数据类型 Interpolate date:用于使能内部插值 Enable zero-crossing detection:用于使能过零检测 Form output after final da...

第一种是Matrix Market (.mtx 格式),中间right hand side 是方程组 Ax=b 的右端项b。 第二种是 Harwell—Boeing 即(HB 格式) .rua 格式 。 注:mtx格式的矩阵就是通常的坐标存储方式,记录所有非零元的行和对应的列,而HB格式是新的存储方式,按照某种压缩原理,记录非零元,简单讲就是HB格式效率更高,同样...
