qr (Matlab function)

Orthogonal-triangular decomposition

Matlab/Scilab equivalent

Matlab

Scilab

X = qr(A)
[Q,R]   = qr(A)
[Q,R,P] = qr(A)
[..]    = qr(A,0)
[Q,R,P] = qr(A, 'vector')
% No equivalent
% No equivalent

[C, R]  = qr(S,B)
[C,R,P] = qr(S,B)
[..]    = qr(S,B,0)
[C,R,P] = qr(S,B, 'vector')

R = qr(A)
[Q,R]   = qr(A)
[Q,R,P] = qr(A)
[..]    = qr(A, "e")
// No equivalent
[Q, R, rk, P] = qr(A)
[Q, R, rk, P] = qr(A, tolerance)

// No equivalent
// No equivalent
// No equivalent
// No equivalent

When used with two input values and tree output values, Scilab and Matlab qr results can differ. Use mtlb_qr instead.
