I am unable to import my csv

It's working here, see below. So, there seems no problem with the file.

How are you reading the file?

Is the file in the current folder? Use the command "pwd" to check what the current folder is.

y = readtable('air-quality-india.csv')

Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

y = 36192×6 table

the filename better be an absolute path, rather than a short form.(like C:\**\**.csv

You can use readcsv or readtable

[Image Analyst]

There is no readcsv, though there is a deprecated csvread which is recommended not to use. I think you meant to use readmatrix or readtable.

Also, specifying the full file name (folder plus base file name plus extension) is a good idea. Use fullfile to do that.

thank you for correction. You 're right
