Read tables in MATLAB
We can use the simple readable command to import the data from a .csv file as a table with column variables (headers). The readable command default detects the file type and makes the first row the column variables if it is in text form.
Syntax
tab = readtable(“file_name.extension”)
See the following example to understand the same.
Example 1:
Matlab
%MATLAB Codetab = readtable("data.csv");disp(tab.Properties.VariableNames) |
In this example, we import a .csv file with numeric data and display its variable names (headers). The following .csv file is used.
Now, the above code will give us the following output:
Further, this data can be manipulated as per the user’s requirements.
How To Import Data from .CSV File With Numeric Values and Texts Into MATLAB Workspace?
A .csv file is a comma-separated file, in which consecutive data columns are separated by commas and the end of a line is the default EOL character. While dealing with small data, it is common to use a .csv file for storing it. In this article, we shall discuss how to import .csv files, with numeric data and their text headers as the column variables, into a MATLAB workspace.
