(50g and Prime): Finding the Moore-Penrose Matrix using LSQ - Eddie W. Shore - 12-16-2014 01:43 PM
Syntax:
M is the matrix with r rows and c columns
HP Prime:
LSQ(matrix, IDENMAT(r))
Where IDENMAT is the identity matrix command.
Path to IDENMAT: Toolbox, Math, 7. Matrix, 4. Create, 2. Identity
Path to LSQ: Toolbox, Math, 7. Matrix, 7. Factorize, 2. LSQ
HP 50g:
2: identity matrix of dimension r x r (R IDN)
1: matrix
LSQ
Build the identity matrix by entering r, then [Left Shift], [5] (MATRICES), [F1] (CREATE), [F4] (IDN)
Path to LSQ: [Left Shift], [5] (MATRICES), [F2] (OPER), [NXT], [F2] (LSQ)
