Hi,
Is there a way to evaluate an equation contained in a string within an AWK script?
For example:
A = "(5*2)-1" (this equation is read from a file and varies line by line)
In this example, I can't see any way to get an answer of 9 unless I do:

! The one-dimensional PDE for heat diffusion equation
! u_t=(D(u)u_x)_x + s where u(x,t) is the temperature,
! D(u) is the diffusivity and s(x,t) is a source term.
! Taking D(u)= 1 and s(x,t)=0 gives
! u_t= u_xx
! uniform one dimensional region |x|<1 for t>0
! uniform mesh size delta x=0.1

I want to automate change in 'from yyyy/mm/dd to yyyy/mm/dd' every month in a unix program.
For example in this month 'from yyyy/mm/dd to yyyy/mm/dd' is 'from 2014/10/01 to 2014/11/01' next month it should be 'from 2014/11/01 to 2014/12/01'
Can any one provide me the code for the above... (2 Replies)
Well guys and gals I have discovered after all these years that Python does complex numbers without the 'complex()' function or 'cmath' import.
It is well known that Euler's Identity E**(i*pi)+1=0 so I decided to experiment
