Import data in MATLAB: importdata Function

You can use the load function to import mat files. But today I get a data file with the suffix '. data '. How should I read it?

I had to use the "Import Data" button in the workspace area of the MATLAB interface to manually import the file. Well, it's okay. It's actually successful. By the way, this "import data" button is very powerful and can be imported into Excel files.

But how to import such non-mat files in the script?

At this time, the "importdata" function is coming!

---------------------------------------------------------------------

Importdata

Load data from File
Syntax

Importdata (filename)
A = importdata (filename)
A = importdata (filename, delimiter)
A = importdata (filename, delimiter, nheaderlines)
[A, delimiter] = importdata (...)
[A, delimiter, nheaderlines] = importdata (...)
[...] = Importdata ('-pastespecial ',...)
Description

Importdata (filename) loads data from filename into the workspace.

A = importdata (filename) loads data into.

A = importdata (filename, delimiter) Interprets delimiter as the column Separator in ASCII file filename.

A = importdata (filename, delimiter, nheaderlines) loads data from ASCII file filename, reading numeric data starting from line nheaderlines + 1.

[A, delimiter] = importdata (...) returns the detected delimiter character for the input ASCII file.

[A, delimiter, nheaderlines] = importdata (...) returns the detected Number of header lines in the input ASCII file.

[...] = Importdata ('-pastespecial',...) loads data from the system clipboard rather than from a file.

This function supports the following file formats: mat files, ASCII files, spreadsheets, images, and audio files.

This ASCII files and spreadsheets refer to: For ASCII files, data contains a double array. other fields contain cell arrays.
for spreadsheets, each field contains a struct, with one field for each worksheet.
