Compile multiple matrices into one without listing them all out

Heya,

I am trying to put a series of matrices into one file. I can do this by writing each of the number in one by one (but there are lots). Is there a quicker way to do this?

My code so far:

numfiles = 60;

mydata = cell(1,numfiles);

for k = 1:numfiles

myfilename= sprintf('40nMket (%d).txt',k);

mydata{k} = importdata(myfilename);

end

%combine

fulldata = [mydata{1,1}.data, mydata{1,2}.data, mydata{1,3}.data, mydata{1,4}.data, mydata{1,5}.data, mydata{1,6}.data]

^how can I do the above final line without typing all numbers up to 60?

Many thanks

"how can I do the above final line without typing all numbers up to 60?"

The general approach is to use a comma-separated list:

https://www.mathworks.com/matlabcentral/answers/1656435-tutorial-comma-separated-lists-and-how-to-use-them

numfiles = 60;
mydata = cell(1,numfiles);
for k = 1:numfiles
    myfilename= sprintf('40nMket (%d).txt',k);
    mydata{k} = importdata(myfilename).data; % changed
end
fulldata = [mydata{:}]

I strongly recommend that you replace IMPORTDATA with READMATRIX.
