Wow good info thanks, i will look into that. About multithreading how would i go about making use of multiple processors?

Fair point, although i am very glad i made the change. As the vba code takes over 2 weeks to run, and C++ takes 3 hours. I would say that is a massive improvement

Getting all info now ( i stupidly had the csv open when running the programme), and is still running at just under 6 mins. Although now i have unchecked the 1st for loop, it will take around 180mins...

Yep, struts definitely confuse me.
Working wonderfully thank you very much for your time and effort

Would these two lines be right?
Previously:
resultsarraystring.push_back (headerarray[q]);
resultsarraystring.push_back (headerarray[c]);
New?

Just as a point of interest. All those for loops iterate 36889042944 times.

I have ran the debugger, it is something to do with the stack. I get this error:

Approx it takes, 0.45 seconds to read and load the intial arrays. Ie dataarray, directionarray & headerarray.

You are absolutely right, very silly of me :) (and a little embarressed lol)
What is the best way to debug in code::blocks?

Your previous code for export to csv file worked a treat, ty very much.
I am getting a few bizarre results though:
With this part of the code:
float t = ( y / z );

Excellent thankyou for the info, i will go through and see which is false more often. That should help a bit at least

Thankyou 2kaud i will give that ago tomorrow, and get back to you with the results
Another thought i had while out running, with this part of the code:
if (dataarray[jRows +...

Good point, for example if i could get the currently 6 mins down to say under 30 seconds i might be tempted to use more data that is available, and those 15's which are minutes, could become singles...

In the global compiler settings, these are the ones that seem to do with optimising. If that is what you mean?
-optimize generated code (for speed) [-O]
-optimize more (for speed) [-O1]...

int currentColumn = someValue;
for ( int i = 0; i < numTotalColumnsInArray; ++i )

if ( i == currentColumn )
continue;
if ( CompareMatrix(currentColumn, i) == whatever )

I have very very few debugging options, most are greyed out. Those that are on in settings are:
- Autobuild project if it is not up to date
- When stopping, autoswitch to first frame with valid...

Here is the updated code:
#include <fstream>
#include <iostream>
#include <sstream>
#include <string>
#include <vector>

January 31st, 2013, 08:37 AM
Sounds fair enough. With the q and c if you look at my little 3x3 matrix above. I compare column1(ie q) with the second and third column (ie c). I then compare column 2 (q) with the first and third...

Okay after lots of searching, got the -ANSI now. And as you said it doesnt like variable length for array

Thats a lot to take in, thankyou for your time.
I am using Code::Blocks editor and on the compiler settings menu, it had automatically selected GNU GCC Compiler. Which compiler should i chose,...

Many thanks for your help.
I have written some code now....and the reading in doesnt actually take long less than half a second. So all the time is going to be taken up with anaylising the arrays...

I understand i need to learn C++ first
But not to worry i have been reading up about reading from csv file. And have written code that reads all the values from the csv file, still a long way to...
