## How to get values of equation group?...

Maple 15

q1.mw

This equations should have numerical solution, but they can’t be calculated. The result is too long, and include ‘RootOf’

It just like this:

> t := 15000; S := solve({n = b+2*c+f+2*g, (a+b+c)/(a+b+c+p+q+f+g) = 5*(1/10), q^2-3.47*p*10^27*t^(3/2)*e^(-10.97*10^4/t) = 0, n*b-(2.407*a*10^21*8)*t^(3/2)*exp(-18.27*10^4/t) = 0, n*c-(1/2)*(2.407*b*10^21*5)*t^(3/2)*exp(-32.035*10^4/t...

My result is complicated, ant it was very large, when I simplified the question, it just as this program.

The main problem is that result in YY is not in order, so the converted result is also disorder, please help me to store the result in order. Thank you!

## How to convert storage type from table t...

Maple 15

Hi！

I get the result which was stored in table, such as:

m:=table([1=[151，153，155，160]，2=[157，152，153，150]，3=[161，158，152，156]])

I can't export it to excel, because the type of m is table, the export  instruction must be array or matrix.

Hi!

I have a problem:

Graph a (in blue) and graph c (in red) are plotted, the value of ax,ay and cx, cy are in list.

program as follows:(also in file q3.mw)

with(plots); ax := [13300, 17400, 12500, 20300, 12100, 22100, 11800, 23100, 11600, 23800, 11400, 24300, 11300, 24700, 11200, 25100]; ay := [.2, .2, .3, .3, .4, .4, .5, .5, .6, .6, .7, .7, .8, .8, .9, .9]; cx := [17700,...

## result storage of for loop...

Maple 15

q2.mw

Hi!

I have a question on result storage of for loop.  The program in attached.

The program is relative complex, it is not necessary to look part 1.

The question is in part 2.

The result I proposed is:

r=([17400,12500],[13900])

but, the real result of r is：

r=table([1.0=[1.0,17400,12500],2.0=[2.0,13900],()=[]])

what should I do to modify the program?
