Hi,
I want to translate some code (which mathgroup helped me to construct) into
C++ using MathCode. It does not understand all the functions in Mathematica,
for instance, it does not take FoldList. Below there is an example of what
I have to do?
FoldList[
#1 + Integrate[
x,
{x, #2[[1]], #2[[2]]}] &,
NIntegrate[
x,
{x, 0, 0.2}], {{a, b}, {c, d}, {e, f}}]
Can you help me getting the same output but avoiding FoldList?
Thanks in advance,
Ruht
