Function Documentation

const Block< const Derived > block ( Index  startRow,
Index  startCol,
Index  blockRows,
Index  blockCols 
) [inline]
Returns:
a dynamic-size expression of a block in *this.
Parameters:
startRow the first row in the block
startCol the first column in the block
blockRows the number of rows in the block
blockCols the number of columns in the block

Example: 

 Output: 


Note:
Even though the returned expression has dynamic size, in the case when it is applied to a fixed-size matrix, it inherits a fixed maximal size, which means that evaluating it does not cause a dynamic memory allocation.

This is the const version of block(Index,Index,Index,Index). 













template<int BlockRows, int BlockCols> 

      

        

          const Block< const Derived, BlockRows, BlockCols > block 
          (
          Index 
           startRow,

          )
           [inline]
        

      






Returns:
a fixed-size expression of a block in *this.


The template parameters BlockRows and BlockCols are the number of rows and columns in the block.


Parameters:

  

    
startRow the first row in the block 

    
startCol the first column in the block

  

  




Example: 


 Output: 


Note:
since block is a templated member, the keyword template has to be used if the matrix type is also a template parameter: 
 m.template block<3,3>(1,1);
