MATLAB: Warning: Out of range or non-integer values truncated during conversion to character.

errorfor loop

Hi I was trying to do this loop.And I got these errors:
'Warning: Out of range or non-integer values truncated during conversion to character. Assignment has more non-singleton rhs dimensions than non-singleton subscripts'
 for mm = 1:4 
    dataset=strcat(DataSetU(num2str(mm)),'M',num2str(mm));
    dataset(1,mm)=[DataBase{1,mm}];
    time=dataset(:,1);
    q=dataset(:,4);
    ....
    theta_param(mm)=(X'*X)^-1*X'*qdot;
end

Best Answer

You use a string as index, that's probably wrong
 DataSetU(num2str(mm))
