Farenheit to Celsius definitely _is_ linear. It's just y = Ax +B. The point, in case it wasn't clear enough already, is that the two texts are contradictory, and that the package description would lead one to believe that it cannot be used for that type of conversion -- whereas it can. fixed in 1.80-3 A linear transformation T has the property that T(x+z)=T(x)+T(z). (That's part of the definition of linear transformation.) If you try your form T(x)=ax+b you'll find that T(x)+T(z)=ax+b+az+b=a(x+z)+2b but T(x+z)=a(x+z)+b. So the property does NOT hold, and hence the form T(x)=ax+b is NOT a linear transformation. The Fahrenheit to Celsius transformation y=ax+b is an affine transformation. http://mathworld.wolfram.com/LinearTransformation.html http://mathworld.wolfram.com/AffineTransformation.html http://algebra.math.ust.hk/matrix_linear_trans/02_linear_transform/lecture3.shtml http://www.instantweb.com/foldoc/foldoc.cgi?affine+transformation *** Bug 100404 has been marked as a duplicate of this bug. *** |
