B and Z must both be vectors or both be matrices.

B and Z must have the same number of columns if they are matrices.

RSD is typically used for computing a correction to Z, where Z has been obtained as an approximation to the solution X to the system of equations AX = B.

Command

 

 

 

 

Type:

 

 

 

 

Description:

Row Swap Command: Swaps rows i and j of a matrix and returns the modified matrix, or swaps

 

elements i and j of a vector and returns the modified vector.

 

 

Row numbers are rounded to the nearest integer. Vector arguments are treated as column vectors.
