Hi, if I have a txt. file with 2 different matrix in the text. file and i want them to be read into matlab, eg:
this is from the txt. file:
% A =
[ 1 2 3 E
5 6 7 E]
% B =
[9 10 11 IX
13 14 15 IX]
and i want matlab to know the diffrent between these two element when it reads the file. so i can make them longer or shorter and it should still be able to take both matrix our with the characters and numbers

It seems all matrices are extracted from the text file except last matrix
% connec
[1 2 1 2e11 A Ix
2 3 2 2e11 A Ix
3 4 3 2e11 A Ix
4 5 4 2e11 A Ix
5 6 5 2e11 A Ix];
It contained numerical with character data thats why it unable to perform
AAA = cell2mat(parts_value);
hence further statements you can't execute
In the cell variable parts_value you can get the all matrices correctly except last matrix as
parts_value{1}, parts_value{2}..parts_value{6}

You could use the import tool and even provide the url of the txt file (https://www.mathworks.com/matlabcentral/answers/uploaded_files/246014/coord2.txt)
You could then set the output type as a table/cell array/ whatever you like and then generate a script for it. You will notice that it eventually uses readtable with some options (not shown below)
% Import the data
coord21 = readtable("coord2.txt", opts);

it does not work for me, it says in the table NaN to all the "letters", but it can load the numbers.
