有没有一种方法可以在Visual Studio调试中打印Armadillo矩阵或矢量? [英] Is there a way to print an Armadillo matrix or vector in Visual Studio Debug?

问题描述

我想知道是否有任何方法可以在Visual Studio(尤其是VS2012)的调试部分中显示矢量/矩阵项的值.

此问题与以下问题非常相似:

有没有办法打印gdb中的犰狳矩阵?

但是我没有弄清楚这种方法是否也适用于VS.

谢谢.

解决方案

此.natvis XML代码在Visual Studio 2013中可以正常工作.我在Visual Studio 2013中添加了@Claes Rolen XML，对我来说这不能正常工作./p>

诀窍是使用<IndexListItems>可视化犰狳矩阵

声明并初始化代码

mat tMat(3, 3);

for (int i = 0; i < 3; i++)
{
    for (int j = 0; j < 3; j++)
        tMat(i, j) = i + j;
}

.Natvis文件

    <?xml version="1.0" encoding="utf-8"?> 
<AutoVisualizer xmlns="http://schemas.microsoft.com/vstudio/debugger/natvis/2010"> 


  <Type Name="arma::Col&lt;*&gt;">
    <DisplayString>{{ Size = {n_elem} }}</DisplayString>
    <Expand>
      <Item Name="[size]">n_elem</Item>
      <ArrayItems>
        <Size>n_elem </Size>
        <ValuePointer>mem</ValuePointer>
      </ArrayItems>
    </Expand>
  </Type>

  <Type Name="arma::Mat&lt;*&gt;">
    <DisplayString>{{ {n_rows} x {n_cols} = {n_elem} }}</DisplayString>
    <Expand>
      <IndexListItems>
        <Size>n_cols</Size>
        <ValueNode >
          mem+($i*n_rows),[n_rows]
        </ValueNode>
      </IndexListItems>
    </Expand>
  </Type>



  <Type Name="arma::subview_col&lt;*&gt;">
    <DisplayString>{{ {n_rows} }}</DisplayString>
    <Expand>
      <ArrayItems>
        <Size>n_rows</Size>
        <ValuePointer>colmem</ValuePointer>
      </ArrayItems>
    </Expand>
  </Type>

调试器中的结果图像:

I'm wondering whether there is any method to show vector/matrix entries values in the debugging section on Visual Studio (in particular VS2012).

This question is very similar to the one posted in:

Is there a way to print an Armadillo matrix in gdb?

however I did not manage to figure out whether this approach also applies to VS.

Thanks.

解决方案

This .natvis XML code works fine in visual studio 2013. I added @Claes Rolen XML in visual studio 2013 and that dose not work fine for me.

The trick is to use <IndexListItems> to visualize armadillo matrix

declare and initialize code

mat tMat(3, 3);

for (int i = 0; i < 3; i++)
{
    for (int j = 0; j < 3; j++)
        tMat(i, j) = i + j;
}
