Hello
sorry for the bad English
Question for hpMuseum forum users, teachers, programmers and other
Is logical that an entry in numerical mode (HOME), have different answer in mode numerical/symbolic (CAS)?
Thanks for your reply
....
Solution, the CAS validate all inputs with the rules of linear algebra and ready, no BUGs =) to whether simple as it does in the mode HOME
considerations, to avoid ambiguity HOME/CAS ...
0: not consider
[] * [] As a dot product, best use dotProd(a, b) command
or use the centered dot symbol // idea
[] . [] == dotProd(a, b)
1: [i, 1] consider it as 2 elementos vector and not as matrix (1 row , 2 columns) //HP48/50 =)
[[ i, 1 ]] // matrix
/////////////
Request #0: display [ a; b; c ] on history like vertical or column vector, purpose pretty print or MathBook
Request #1: use |vector or matrix | as absolute value element to element, and not as vector norm
idea double symbol || as norm
|| vector or matrix || like MathBook
Request #2 new command (.= or .== ) for to compare element by element
( vector or matrix .= vector or matrix )
Request #3 use true/false (keyword current) logic value instead of 1/0, is more intuitive true/false for a beginner user, or by an flag enable output numeric or keyword
Request #4 use e. as an approximate value
Thanks
