在使用MATLAB读取txt文件并绘图时,首先需要将txt文件复制至MATLAB的工作目录,或者通过设置路径指向txt文件所在的路径。接着,右键点击该txt文件,选择“Import Data”选项。在弹出的导入向导中,选择Matrix作为数据范围,点击确定按钮,即可将txt文件中的数据导入到MATLAB中。导入成功后,在工作区中会看到 ...
csvwrite(filename,M) writes matrix M to file filename as comma-separated values. example csvwrite(filename,M,row,col) writes matrix M to file filename starting at the specified row and column offset. The row and column arguments are zero based, so that row=0 and col=0 specify the...
