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

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

Give us the line and the error in context at least as a start instead of making us try to divine the problem...

Sorry the line that cause the error I think is:

 dataset=strcat(DataSetU(num2str(mm)),'M',num2str(mm));
 dataset(1,mm)=[DataBase{1,mm}];

When I run I get on the command windows only that "Warning: Out of range or non-integer values truncated during conversion to character. Assignment has more non-singleton rhs dimensions than non-singleton subscripts"

It doesn't tell me where :S

You use a string as index, that's probably wrong

 DataSetU(num2str(mm))

[Andil Aboubakari]

 num2str(mm)

is meant to give DataSetU a different name each loop rather than indexing.

Bad syntax to do that and bad idea, anyway...
