I have a program which does some calculations. At some point, one has to take two values, lets say Nr and Dr having values 7.3331415e+06 and 45.7275009, respectively. It has to be multiplied by (5*MassOfProton^2)/(Charge^2). For this set of parameters, the correct answer is 8.74061*10^-11. But Matlab approximates to zero. I need that particular value. How can I do this?
The code is given as below:
clc
format long
mp=1.6726*10^(-27);
qCharge=1.602*10^(-19);
Nr=7.3331415e+06
Dr=45.7275009
(5*Nr*mp^2)/(Dr*qCharge^2)
I have looked into various solution given here and here, but did not get any solution. Any help will be deeply appreciated! Thanks in advance **************************************************
Edit 1:
After reading the comments and answers, I realised something strange.
Well, the values of Nr and Dr is 26th element two different 1x72 single array, which I have loaded into MATLAB workspace from a CDF file.
i.e.
Nr=Array1(26);
Dr= Array2(26);
When I am using this instead of the exact value that is seen at the specific location (i.e. 26th column), I am getting zero. But If I am using the numbers which I had copied from that exact location (just like as I shown in my earlier code), I am getting the answer 8.74061*10^-11, as mentioned earlier. Further, in the long run, I am planning to replace iterate over so that 26 will be replaced by i.
One more information (not sure whether useful or not): I went and looked into CDF file and found that there is a column titled ‘FORMATS’. In it, it is shown that the FORMAT corresponding to Nr is 'E12.2' and that of Dr is 'E8.2' (not pretty sure what they are). Further, 7.3331415e+06- Array1(26) gives me zero, while 45.7275009- Array2(26) gives me a small finite value “-1.5527341e-08”
Edit 2:
Appending 'Array1' and 'Array2' mat file for testing (Sorry, didn't knew earlier that there was a provision to save the variables :) )
