MathCompute Program[update on 2006.2.23].

Runing under windows98/ME/NT/XP , Delphi7

A program used to compute algebraic expression including Determinants.

This porgram is just the first one , we willl made it more powerful soon.

 

useage:

edit a file named C:\mathcompute.txt like this:

———————————————

know:
D1(D)=
0   0   2   -1   4
2   0   1    2   1
-1  0   5    1   2
3   0   1    2   1
2   0   0    3   5

D3(D)=
1   1/2   0   1    -1
2   0     -1  1    2
3   2     1   1/2  0
1   -1    0   1    2
2   1     3   0    1/2

solve:
D1*(1/2)+(D3*2)=?

—————————————— 

then run the program you will see :

solve:

[3/4]q

 

the keywords is solve: under it must be a algebraic expression

———————————————

allow using variables in "know:", for instance, you can edit "mathcompute.txt" like this:

—————————————— 

know:
x=1
y=2

A(D)=
1  0  0 y
x  4 2
4  5  x 1
9 x+y 7 2

 

B(D)=

1 2

A 3

 

solve:
(A-B*2+1)/5=?
—————————————— 

here "x"and"y" are variables.

the program will give you the answer: [204]z
