Dear all,
I would like to read in a txt file (see attached document) the 55x55 matrix using matlab.
In the txt file, the matrix appears in a block of 9x6 followed by one line (which then accounts 55 values) . And there are 55 blocks like this.
In fact, this block contains averaging kernel values for the 55 pressure levels of the sounding instrument.
How can I read this gile so I have at the end a matrix called A which has a dimension of 55x55?
Thank you for your help,
Best regards

How about the following?
A = readmatrix('Averaging_kernel_MLS_v04_0N.txt');
A = reshape(A',60,[])';
A = A(:,1:55);

Both end up the same in the end...
>> B=readmatrix('Averaging_kernel_MLS_v04_0N.txt');
>> B=reshape(B.',60,[]).'; B=B(:,1:55);
>> all(A(:)==B(:))
ans =
It's just perhaps a little cleaner w/ textscan. Too bad TMW hasn't added the ability to pass a filename as alternate input besides just a file handle so could avoid having to have the encapsulating fopen...fclose pair.
