matlab - how to solve something associated with memory and speed of my computer? -


First of all, I have a special task that works at the cost of every possible combination of category, I already A program that my purpose is to do this code: 

  clc one = clear the input ('please, select your array:') b = a (:). 'C' for length (b) d = 1: c if (d & lt; c) e {d} = nchoosek (b, d); End (m, 2)], 'post' (e), e, 'uniform output', 0); Uu = cell2mat (tt ([1: d-1])) suu = size (u) u (:, (suu (2)) + 1) = = sum (uu) '

But during the implementation of this program, I had to face a major problem: 

  e {d} = nchoosek (b, d)

The number of possible options and the number of selected options and ultimately failed to continue as a result of boundaries:

When b = nchoosek (n, k) Is larger than, nchoosek shows a warning that the result can not be accurate In case of the case, the result is only 15 digits for double-precise input or 8 digits for a single-precise input.

C = nosacec (v, k) Is only practical for circumstances where the length (V) is less than 15.

This is where my vector is consisted of hundreds of numbers, which I want to do on this process. If I run the program, then the matlab will take me out of memory error at a time Appropriate stays and takes time without the implementation of the program, then forced me to get out of the program. I searched for a solution through "out of memory" help but I failed to find any sort of solution, then I tried to use any other command which is 

  Combnk (v, k)

but takes time without the execution of the program, so please force me to get out of the program. Please, Executing a lot of processes I want to make a practical solution for If the solution depends on the capabilities of my computer, then tell me about computer specifications that easily performs this program, quickly and immediately note that my computer specification is: Win 7 64 bit 4GB RAM 2.3 CPU I3

Member with no value in F# -

After I am trying to convert F # to the following C # code: [StructLayout (LayoutKind.Sequential, charset = CharSet.Ansi)] Private class DOCINFOA {[MarshalAs (UnmanagedType.LPStr)] public string nomeDocumento; [Marshall (UnmanagedType.LPStr)] Public string arquivoSaida; [Marshall (UnmanagedType.LPStr)] Public String Tipodo; } I am doing the following: Named place printer module RawPrinterHelper = [& LT; StructLayout (LayoutKind.Sequential, charset = CharSet.Ansi) & gt;] Type DOCINFOA = [& LT; MarshalAs (UnmanagedType.LPStr) & gt;] Member this.nomeDocumento [& LT; MarshalAs (UnmanagedType.LPStr) & gt;] Member this.arquivoSaida [& LT; MarshalAs (UnmanagedType.LPStr) & gt;] Member This Tipoda [/ code> But I get: One type of definition is necessary for one or more members . Can I vacate these members? you val code> member : [& lt; StructLayout (LayoutKind.Sequential, charset = CharSet.Ansi) & gt;] Type DOCINFOA = [...

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
