At the request of some of you, here are a few things that you may be interested for this September:
Some notions on matrices:
There are many ways to create arrays in the HP, the most visually intuitive and more comfortable (at least for me) is with Focus on the left SHIFT + '(MTRW), just select the appropriate box, enter the value and hit ENTER, once completed, return to press ENTER on an empty square. I appear on the matrix screen itself, which if you have to operate with it, yours will be that the almacenéis in a variable, that is, when you have in your screen, press STO-> and a letter (ALPHA + a letter). Be stored on the drive letter, and you can access it by viewing the variables (VAR key), selecting it as appropriate with the corresponding function key.
Note: Please note that if you have activated complex mode and do an array of one row and two comlumnas, the calculator automatically transforms a complex number
To operate with matrices and matrix functions, the manual contains pages and pages and pages, and highlight only the most relevant, I advise you to take a look at the menu MATRICES (Focus on the left SHIFT + 5), especially the option 7, the eigenvectors, which opens up a whole new menu on the diagonalization of matrices:
PCAR (X): It returns the characteristic polynomial of the matrix X
EGVL (X): It returns the eigenvalues \u200b\u200b(eigenvalues) of matrix X
EGV (X) values \u200b\u200band eigenvectors of the matrix X
JORDAN (X): This is the most completita, and gives us the following information from the matrix X:
• The minimum polynomial matrix
• The characteristic polynomial matrix A
• A list of the eigenvectors that correspond to each value
own matrix A
• A vector with the eigenvectors of the matrix A
Other utilities that have asked are:

This is what best fits what you asked, I hope you like! Pass
good summer (which is ...)!
