MathReader 4.2 --- Mac OS X (10.2.6) does not read Notebooks correctly I received a number of Notebooks which seem o.k, to read on Mathematica 4.0 on Mac OS 9 (may be after conversion). As I do not have this on my personal MacOS X, I installed MathReader (4.2). This shows the nb inadequately. Probably some fonts are missing (which MR does nor install?) Is this usual? Which fonts are missing or ar not found by the application (also after restart)? And where to find them if they need to be installed? I could send the notebooks if you provide an email address. I am not sure if this cell helps to answer my question: Kronecker delta functionWe start by defining the Kronecker delta function. We will use it to input the matrix elements of the raising and lowering operators.\[Delta][n_,n_]:=1\[Delta][n_?IntegerQ,m_?IntegerQ]:=0The tests with IntegerQ leave \[Delta][m, n] unevaluated when m and n remain unspecified for symbolic computing:{\[Delta][1,1], \[Delta][2,3],\[Delta][m,n]}{1,0,\[Delta][m,n]}We can then substitute for m and n later on:%/.m\[Rule]n{1,0,1}This is just a compact version of the built-in function KroneckerDelta. The first Delta shows as dBn_, n:F := 1 dBn_? IntegerQ, m? IntegerQF := 0
