how to solve this problem? with message subscript indices must either be real positive integers?

Hello, I get this error, Subscript indices must either be real positive integers or logicals.

The line with this error is,

    An=110;
    Am=100;
    DUM(100,An/(Am+1)+1)={''};

The index you’re calculating evaluates to 2.0891... so as a float, it definitely does not meet the integer-or-logical criterion.

I’m not certain what you’re doing with your indices, but one option would be to use the fix function to produce an integer index:

DUM(100,fix(An/(Am+1))+1)={''};

Other options, if fix does not produce the result you want, are of course are ceil, floor, and round.
