Detailed Description

template<int _OuterStrideAtCompileTime, int _InnerStrideAtCompileTime>
class Eigen::Stride< _OuterStrideAtCompileTime, _InnerStrideAtCompileTime >

Holds strides information for Map.

This class holds the strides information for mapping arrays with strides with class Map.

It holds two values: the inner stride and the outer stride.

The inner stride is the pointer increment between two consecutive entries within a given row of a row-major matrix or within a given column of a column-major matrix.

The outer stride is the pointer increment between two consecutive rows of a row-major matrix or between two consecutive columns of a column-major matrix.

These two values can be passed either at compile-time as template parameters, or at runtime as arguments to the constructor.

Indeed, this class takes two template parameters:

Template Parameters
_OuterStrideAtCompileTimethe outer stride, or Dynamic if you want to specify it at runtime.
_InnerStrideAtCompileTimethe inner stride, or Dynamic if you want to specify it at runtime.

Here is an example:

int array[24];
for(int i = 0; i < 24; ++i) array[i] = i;
cout << Map<MatrixXi, 0, Stride<Dynamic,2> >
(array, 3, 3, Stride<Dynamic,2>(8, 2))
<< endl;
