I loaded a data file, but why is matlab not able to name the different columns of data within the txt file?

I had a csv file with about 10 columns of data, each column is a set of values monitored over a certain amount of time; 1st column is time, 2nd column is speed 3rd column is altitude, etc...
the csv file was converted to a txt file and then loaded on Matlab (no errors at this stage), but then when I try to define the different columns it comes up with an error (Index in position 2 exceeds array bounds).
the code is:
load MONDOteam_26.txt %name of the file
SIM22time = MONDOteam_26(:,1) %define 1st column

"the csv file was converted to a txt file ..."
CSV files are text files, so that statement does not mean much. Do you mean that you changed the file extension?

It would be best not to convert the .csv file to a text file (or to anything else) initially.
Instead, use readtable to read the original .csv file with its single-line headings (variable names). Then, you should be able to work with it.
If you are not used to using table arrays, see Access Data in Tables to understand how to work with them.
