incorrect reading of a txt file

5 views (last 30 days)
I have this .txt file that I have to read in Matlab. The first line is text and the second line onwards are numbers.
Using 'importdata' I do not get the desired result. How come?

I am not sure what the expected output is supposed to be, but you can use readtable -
in = readtable('test.txt','DecimalSeparator',',')
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.
in = 3×9 table
