Finding highest numbers between arrays?

string   jPairs[28] ={"USDCHF", "EURGBP", "GBPUSD", "NZDUSD", "EURJPY", "AUDJPY", "GBPJPY", "AUDUSD"......to 28 pairs};
//some code
 for(int i=0; i<ArraySize(jPairs); i++)
if (i < 8) {
//your code.....

This is the way I think it goes.......... string jPairs[28] ={"USDCHF", "EURGBP", "GBPUSD", "NZDUSD", "EURJPY", "AUDJPY", "GBPJPY", "AUDUSD"......to 28 pairs}; //some code for(int i=0; i<ArraySize(jPairs); i++) if (i <= 8) { //your code.....

I have double numbers such below. I want to code exactly that, sort this numbers and take only first 8 numbers from inside 28 pairs for every candle and create new two dimentional array x[1,1]= 0.9876 x[1,2]= 0.5646 x[1,3]= 0.3456 x[1,4]= 0.2346.... x[1,28]= 0.4565 x[2,1]= 0.1234 x[2,2]= 0.5678 x[2,3]= 0.9012 x[2,4]= 0.3456.... x[2,28]= 0.7890 x[3,1]= 0.2345 x[3,2]= 0.6789 x[3,3]= 0.7890 x[3,4]= 0.8901.... x[3,28]= 0.9012 . . . . . . . {quote}

{quote} you are not being too clear about your needs, there are various ways of doing it but it depends on what you need to know ie: 1. do you want to know the array positions holding the highest 8 or just the highest 8 numbers? 2. is that highest 8 numbers for each of the 28 1st dimensions or across all 28 ie: 28x8 answers or 8 answers? Some simple facts: You cannot sort on anything other than the first dimension of an array.... a way around this is normal to have a separate array for each of the 1st dimension elements ie: 28 separate arrays in...

hi MaxDoom, sorry for unclear explain!! i have 28x500 array, now want to generate 8x500 array. These 8 comes from sorted 28 that means the first 8 values of 28. Can you post some sample codes? Thanks {quote}

{quote} okay but how are you selecting the 8 from 28 each has 500 numbers in the second dimension

{quote} Ok, every 28 have 28 values such as 1) 0.9876 2) 0.7896 3) 0.4567 ......28) 0.1234 i want to collect only first 8 sorted values. Higher values only.

{quote} you need to be clearer here, 28 of 28?? you have a two dimension array for example: double BigArray [28][500]; the first dimension does not store anything it is just the reference numbers 0-27 the second dimension has the 500 (0-499) double values in for each of the 0-27 references so if you want the top 8 of the first dimension you somehow want to compare some or all of the 500 values for each of the 28 first dimensions. the table shows what the array might look like now you need to be clear, you want to select 8 of the 28 arrays but how...

{quote} sorry not clear at all? you want to select 8 of the first dimensions I get that, each of the 1st dimensions has 500 elements but what are you trying to sort? look at the table I done are you trying to sort: 1) left to right ie: for each 1st dimension sort the 500 elements high to low or 2) top to bottom each column of 28 elements (if so how many columns just the first one?) or 3) the entire 28x500 elements all together ?

{quote} that makes no sense chap, I am trying to help you and can give you some code but you need to explain properly the array has 28 rows with 500 columns in each row. you want to select just 8 rows you cannot sort all 500 columns that would be meaningless as the data is in sets of 28 and would become just random. do you need to sort each row of 500 elements or is their order okay? now to select the best 8 you want the highest 8 rows but highest of which column, 0 I presume? explain with the table I did for you or by being clear, otherwise sorry...

if that is really what you want then it sounds like your data is organised wrong, that is a massive task to sort 28 times 500 elements from 28 different dimensions even then you have still not said how you would select the best 8 rows, which would now no longer contain sets of 500 data elements but random sub-sets of 14,000 elements... I think that you need to either rethink it or use a small excel to show what you mean, like the table I did for you clearly showing what you are going to sort and which rows you pick and why.

ensark, I guess the difficulty here is because English is not your first language. If you know somebody who is really fluent in the English language, maybe you can get them to translate exactly what you want.

1. I have 28x500 array
2. i want to sort every column(we have 500 columns and just sort these columns!!) (sorting every column with 28 values)x500
3. create the second array as 8x500 and copy values 8x500 from table 28x500.
