But you are not comparing like products. The signal processing toolbox is
not a part of core MATLAB. It is an additionally priced product and you
have to pay extra maintenance to keep using it.

Really?
Please explain how the following demonstrates the superiority of MATLAB 6
over a quite old version of IDL:
< M A T L A B >
Copyright 1984-2000 The MathWorks, Inc.
Version 6.0.0.88 Release 12

>> i=int16(1);
>> i=i+1;
??? Error using ==> +
Function '+' not defined for variables of class 'int16'.
>> i
i =
1
IDL Version 5.1.1 (IRIX mipseb). Research Systems, Inc.
IDL> i=fix(1)
IDL> i=i+1
IDL> print,i
2
To me, any product which can't do a simple 1+1 is not worth considering for
data processing.
