We may also say that 'x_sol' has 1x9 cells, so the first cell has one array, second cell also has one...and so on, we have 9 arrays in 9 cells. I believe we can call the array a cell matrix as well. 댓글을 달려면 로그인하십시오....
运行MATLAB程序,点击工具栏上的Import Data工具按钮。 在弹出的“Import Data”对话框中找到前面保存的数据文件(B.xls),“打开”。 弹出“Import”窗口,在窗口工具栏左侧导入选项中选择“Matrix(矩阵)”,然后点击工具栏右侧的“勾”,导入数据。 关闭“Import”窗口,回到MATLAB主程序,在WorkSpace(工作空间)中可以看到...
● M = csvread('filename', row, col),读取文件filename中的数据,起始行为row,起始列为col,需要注意的是,此时的行列从0开始。 ● M = csvread('filename', row, col, range),读取文件filename 中的数据,起始行为 row,起始列为col,读取的数据由数组 range 指定,range 的格式为:[R1 C1 R2 C2],其中...
I have tried it with these files and only I got it with csv file. What is the rule for read these files in this way? 2 Comments Doug Hullon 2 Feb 2011 What is happening when you fail? When you say "read as a matrix" do you mean "read as a vector"?

创始: MATLAB(Matrix Laboratory 的缩写)最初是在1970年代末由Cleve Moler开发的,他当时是新墨西哥大学的计算机科学教授。Moler 开发 MATLAB 主要是为了让他的学生们更容易地访问LINPACK和EISPACK项目而不必学习Fortran语言,这两个项目都是进行矩阵计算的数学软件包。它迅速在应用数学和工程领域中变得流行起来。

CSVREAD用来读分隔符是逗号的文件,是DLMREAD的特殊情况。当读空格和Tab分隔的电子数据表文件时,DLMREAD特别有用。以'sample_file.txt'为例: CODE: Example 1: Using DLMREAD to read in a file with headers, text, and numeric data % This reads in the file 'sample_file2.txt' and creates a matrix,...
