How to use different size features in SVM?
I think you have a misconception.  SVM does not necessarily give the latter 58 features a weight of 58/59.  Rather, SVM learns what weights to use for each feature, based upon what helps it build the best classifier.

So, just use those features and train with them.  Don't try to find a way to manually provide different weights for the features; SVM training automatically takes care of that for you.
