MATLAB: How to read the entire contents of a file into a cell array with one line per cell

MATLAB

I would like to read the entire contents of a file. In the end, I'd like to have a cell array, where each cell contains a line from the file.

There is no single function that does this in MATLAB, although several functions can be combined to do this.

For instance,

str = fileread('foo.txt');
lines = regexp(str, '\r\n|\r|\n', 'split');

reads "foo.txt" into a string, and then splits the string into cells according to newline combinations.

filename = 'YourFile.txt'
S = regexp( fileread(filename), '\r?\n', 'split');
S(cellfun(@isempty,S)) = [];    %remove empty lines, especially at the end

Now S will be a cell array of character vectors. It will not be a cell array of string objects because MATLAB uses either cell array of character vectors, or else uses string() arrays. You can convert it to a string array by using string(S)

The last half of your code should be revised, like:

% Get the value out of a cell
a = str2num(cell2mat(B));
% Make an numeric array from 1 to a
K = 1:a;
