qr

Orthogonal-triangular decomposition

C++ Prototype

mwArray qr(const mwArray &in1,
           const mwArray &in2=mwArray::DIN,
           const mwArray &in3=mwArray::DIN);

mwArray qr(mwArray *out1,
           const mwArray &in1,
           const mwArray &in2=mwArray::DIN,
           const mwArray &in3=mwArray::DIN);

mwArray qr(mwArray *out1,
           mwArray *out2,
           const mwArray &in1,
           const mwArray &in2=mwArray::DIN,
           const mwArray &in3=mwArray::DIN);

C++ Syntax

#include "matlab.hpp"

mwArray X;             // Input argument(s)
mwArray R, E;          // Output argument(s) 
mwArray Q, A;          // Return value

Q = qr(&R,X);
Q = qr(&R,&E,X);
Q = qr(&R,X,0);
Q = qr(&R,&E,X,0);
A = qr(X);

MATLAB Syntax

[Q,R] = qr(X)
[Q,R,E] = qr(X)
[Q,R] = qr(X,0)
[Q,R,E] = qr(X,0)
A = qr(X)
