Numerical Diff. EQ. Solver not working.
|
| |
I'm probably doing something wrong, but I wanted to test out an equation in the solver under NUM.SLV>diff eq.
I entered my equation on the top '2*X^2+Y^3'
indep: X init:1 Final:2
Soln: Y init:2 Final:
Tol:.0001 Step:dflt When I hit solve, it sat there for several minutes before I stopped. It was thinking the whole time but I'm not sure what it was doing. I was just wondering if this was a bug or if I forgot to set a flag correctly. Also, if I enter step:1 would it give me a solution as if I had use Euler's method?... more »

Recording calc commands (like macro, but editable)
|
| |
In excel vba, when we record a macro, the vba code gets recorded and
we can go back and edit it later using program editor to further
customize the program. This is a fantastic way for quickly/
effectively generating a program imo because it allows us to use the
native (excel) environment in the way we are used to with immediate... more »

RPL+ news
|
| |
I've spent more hours than I care to think about on designing and
implementing RPL+ last year.
For the first time since inception, the documentation has caught up
with the implementation...
If you're interested, here're three links:

Getting a 1..100 vector
|
| |
Does someone see a better way to get a vector [1..100] than using one
of these snippets?
≪ ≪i≫ 'i' 1 100 1 SEQ AXL ≫
≪ { 100 } 0 CON 1 AXL ≪ DROP NSUB ≫ DOSUBS AXL ≫
Thanks.

hp50g left arrow key
|
| |
The up, down, and right arrow keys on my 50g work well. In edit mode,
an arrow key closure moves the cursor 1 position first time every
time.
The left arrow key did not feel different but the operation was
erratic. A key closure might or might not move the cursor.
Opening the case was beyond my ability.... more »

How to transfer formulas from HP 50g to Matlab?
|
| |
I did some symbolic calculations using inverse Laplace transform. I've
got a function that describes how a circuit works and now I want to
enter it into Matlab to do numeric calculations and to build graphs.
The problem is that my function is very big and if I enter it manually
I can make too many errors. So the question is how can I transfer a... more »

MSLV input
|
| |
From the CAS help and HLP49, MSLV accepts an input like this:
3: [ 'EQ1' 'EQ2' .. ] n equations
2: [ 'var1' 'var2' .. ] n unknowns
1: [ var1guess var2guess .. ] initial guesses for the aforementioned
variables
Given Rouche-Capelli conditions are satisfied,problem is converging,a
solution exists and the guesses are in a converging zone,it converges.... more »
