Warning, do not run this before saving your work: In:= ClearAll["Global`*"]; expr = 0.20056791381984598*I*E^((-2.3120000000000003 - 2.4929211780559766*I)*n) - 0.20056791381984598*I*E^((-2.3120000000000003 + 2.4929211780559766*I)*n); ZTransform[expr, n, z, Method -> "Holonomic"] *kernel crash* But when I do ZTransform[expr, n, z] I was getting errors General::lrgexp, but no crash. The above is an expression generated internally from a program I am working on, depending on the input parameters, sometimes I get these errors and sometimes I do not, since the expr will be different each time depending on the parameters that are entered. So I was trying to find where the error was coming from. I do not really understand why this error message is coming. Must be something internal to Ztransform. I will send a bug report to WRI support also. --Nasser
