It appears the data is not separated into columns. Any way to do this?
A = importdata('Psmall.txt');
A1 = A(:,2);

It's returning a column vector with all values (i.e. 22... 3.3...) as if both columns of numbers are within one column. Thanks for trying it for me.

To be clear, when I run your code, I get an Nx2 matrix (of data type "double"). As Star Strider said, it is then easy to separate them into the column vector.
Is that what you get?

You were both correct, I had it right in the original code. Sorry for the confusion. Thanks for your responses!

Hi Charles Naegele
1.
You are having the same result as if you were using textscan instead of importdata
fid1=fopen('Psmall.txt');
B=textscan(fid1,'%s');
fclose(fid1)
B1=B{1}
B2=cell2mat(B1)
B2 has as single column with all data, as you mention it happens in your data acquisition.
2.
Try
A=importdata('Psmall.txt','\t')
Note that your data file has a TAB as separator, not the default ' ' (space) or comma. Despite MATLAB help for import data reads
The default character is interpreted from the file.
It may be the case an earlier version of MATLAB doesn't really consider TAB as a column separator.
If you upgrade your MATLAB version you will solve this and possibly other compatibility issues to come.

Turns out I had it correct in the original code, but I thought this answer might be useful to someone else in the future. Thanks!
