Themen

Lesen von Daten in Kalkulationstabellen

Import Spreadsheets
Spreadsheets, such as Microsoft Excel files, often contain a mix of numeric and text data as well as variable and row names.
Read Spreadsheet Data Using Import Tool
Preview spreadsheet data from a file or the clipboard and select data to import using the Import tool.
Read Spreadsheet Data into Table
The best way to represent tabular spreadsheet data in MATLAB is in a table since tables can store heterogeneous (a mix of numeric and text) data, as well as variable and row names.
Control How MATLAB Imports Your Data
If you want to control the import process beyond the options provided by the readtable function, such as defining how to handle missing data or errors, then create an import options object before importing the data.
Read Spreadsheet Data into Array or Individual Variables
In addition to importing data as a table using readtable, you can also import data as a matrix, a cell array, or import separate variables directly in to the workspace.
Read Collection or Sequence of Spreadsheet Files
Read and manage data from a collection of spreadsheet files.
