Hi
I'm an electrical engineer who wants to choose a calculator
to buy. I want to know whether the classPAD300
does the following or not:

1. Matrix operations on matrices with parametric elements
(non-numerical)
2. Solving system of differential equations
3. Solving system of equations with parametric coefficients

I'm trying to make a decision between classPAD300 and TI89
what's your idea??

I will appreciate your help

Hi i'm a electronic engineer student. The classpad is a great tool for engineering, but its oriented to educational. Thats no problem because some of the things that the classpad dont have you can do it in a casiobasic program. Wait for more replies, i'm sure that other guys had more things to say about this.

Personally i like more the classpad, thats the reason i bougth one . Also classpad have a lot of memory and a bigger display. I hope that you make a good decision.

the classpad can do the three, but i don't know how far

one thing you should know, the current version of the classpad has a bug in the matrix system, it will be fixed in the first OS release. the problem occures in large matrixes acsessed in a program but not in the main area so if you dont need to write programs your fine.

btw: i didnt know the classpad could have non numeric values in the matrixes... how do you do that?

[Overlord]

a parameter is a numerical variable/constant known or not known but you use the letter instead of the number

it is non sense to perform math matrix operations with strings
