I want to read the txt file with the "textscan" method, but my code is not working. I get this error message whenever i try to compile the script.

"Conversion to double from cell is not possible.

Error in Untitled (line 10)
        x(i,pat)=(Data(i,pat));"

This is my code

fh=fopen('OrdonezA_ADLs.txt');
Data=textscan(fh, '%s,datenum(%s),%s,datenum(%s),%s');
fclose(fh);
n=length(Data);
P=length(Data{1});

x=zeros(n,P);
for pat=1:P
    for i=1:n
        x(i,pat)=(Data(i,pat));
    end

end

Try this:

Data=textscan(fh, '%s%s%s%s%s');

You may need other name-value pair arguments such as 'Delimiter', 'MultipleDelimsAsOne', CollectOutput, and others.

Also, it is best to use the size function here:

n=size(Data,1);
