Reading in a text file and creating multiple arrays

I have a large text file. The first two lines appear as follows:

// cor=0.2 n=4000  N=10000
// r u_effe averg

Below that I have a bunch of lines of text with 4 columns. Then after the block of code finishes, I have 2 blanks lines, and then another 2 lines of code as above, but with cor=0.3. This goes on and on. Can I load this txt file into MATLAB and break up these into arrays with the different arrays named cor-0.2, cor-0.3 etc?

I have attached some sample code

You can use the same kind of technique I showed in https://www.mathworks.com/matlabcentral/answers/447889-how-do-i-read-data-from-a-dat-file-seperated-by-lines-of-text-into-individual-vectors#answer_363508

I am currently just copying it manually, I haven't been able to get it to work. I tried playing the import tool, but couldn't find anything that would split it up how I want.

[Walter Roberson]

import tool cannot do the work.

You should avoid writing to separate variables; see http://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval

Do you need to preserve any of the numbers from the cor= line? Or just the numeric array below that?

I just put the data into excel. Is there a way that I can load each worksheet into MATLAB and store each as a separate array? I ultimately want to be able to loop through them.

I think I got it:

[~,sheet_name]=xlsfinfo('filename.xlsx');
for k=1:numel(sheet_name)
  data{k}=xlsread('filename.xlsx',sheet_name{k});
end;
