I am trying to solve for pTyr50for100 this FOR loop with three
different variables (KmPdephos,Kcatautophos, Kcatphos). I basically
want to calculate the value of pTyr50for100 for different combinations
of these variables as defined in the loop However, once the innner loop
is completed the value of the inner loop variable remains steady at the
final value and that loop is exited. There is a logical error in this
code which I havent been able to find and I was hoping someone could
help me with it. To make things clearer heres the code
For[dimKcatautophos = 0.0008;
For[dimKmPdephos = 0.01;
For[dimKcatphos = 0.008; ndsolutioncombined, dimKcatphos < 0.8,
dimKcatphos += 0.1, pTyr50for100 = {dimKcatautophos/0.0008, \
dimKmPdephos/0.01, dimKcatphos/0.008, ((Lphos[50] /.
ndsolutioncombined)/3)*100}; Print[pTyr50for100]],
dimKmPdephos < 1, dimKmPdephos += 0.3, pTyr50for100 = \
{dimKcatautophos/0.0008,
dimKmPdephos/0.01, dimKcatphos/0.008, ((Lphos[50] /. \
ndsolutioncombined)/
3)*100}; Print[pTyr50for100]],
dimKcatautophos < 0.08, dimKcatautophos += .1,
pTyr50for100 = {dimKcatautophos/0.0008, dimKmPdephos/0.01,
dimKcatphos/0.008, ((Lphos[50] /. ndsolutioncombined)/3)*100}; Print[
pTyr50for100]]
ndsolution:= a set of 20 differential equations
The output from this is
0.0008, 0.01, 0.008, {value at this condition)
0.0008, 0.01, 0.108, {value at this condition)
0.0008, 0.01, 0.208, {value at this condition}
... 0.308 .......... Here the
Value of inner loop is changing as anticipated
.... ......... 0.408............
.... ........... 0.508................
.................. 0.608
.... 0.708
...... 0.808
0.0008, 0.31, 0.808 But here I would
expect the inner loop to be evaluated after the increment in the middle loop
0.0008, 0.61, 0.808 Instead the
inner loop value is constant (max value) and middle loop is evaluated
