（3）M = csvread(filename,R1,C1,[R1C1R2C2]) reads only the range bounded by row offsets R1 and R2 and column offsets C1 and C2. Another way to define the range is to use spreadsheet notation, such as 'A1..B7' instead of [0 0 6 1].解释如下：M = csvread(filename)：导...
接下来,在Python脚本中,我们使用如下代码读取刚才保存的CSV文件: importpandasaspd# 读取CSV文件data=pd.read_csv('data.csv')# 显示读取的数据print(data) 1. 2. 3. 4. 5. 6. 7. 这段代码将会从data.csv文件中读取数据,并将其保存在名为data的DataFrame中,随后打印出内容。 步骤4: 数据预处理和分析...
要从CSV 和 Microsoft Excel 文件导入文本,请使用readtable。 要从HTML 代码中提取文本,请使用extractHTMLText。 要从PDF 表单中读取数据,请使用readPDFFormData。 文本文件 用extractFileText,从sonnets.txt中提取文本。文件sonnets.txt包含纯文本形式的莎士比亚十四行诗。
