Hi all,

I am interested to find documentation from internet in using Maplesim for power electronics simulations. Like Gradators and frequency variators etc...

I can not find any documentations.

Could you if exist any web site for modeling in power electronics and perhaps with Maplesim

Thanks in advance for any help

Hi all,

I have this function:

restart:

I2:=g->(200*g)/sqrt(0.04+g^2);

plot(I2(g),g=0..1); 

plot(I2(g),g=1..0);

Those two plots give the same result.

Is it possible to invert the x axes to start from 1 ?

I also tried this below, but the result is as above.

x:=seq([g,I2(g)],g=1..0,-0.02);

pointplot([x],style=line);

Thanks

Hi all,

To share a maple document, I found this Maple help.

To share worksheet content:
1. In Maple, open the worksheet that contains the content you want to share.
2. If you want to share a worksheet selection, select the text and objects in the worksheet. If you want to share an entire worksheet, you do not need to select any text or objects in the worksheet.
3. Expand the MapleCloud palette.
4. From the drop-down list in the palette, select...

Hi,

How to load Maple-NAG connector to execut this example ?

Is it an additional program to install ?

n := 4:
nnz := 11:
la := 22:
lfill := 1:
dtol := 0:
pstrat := "Nag_SparseNsym_CompletePiv":
milu := "Nag_SparseNsym_UnModFact":
a := Vector[row](la,[1.0,1.0,-1.0,2.0,2.0,3.0,-2.0,1.0,-2.0,1.0,1.0],datatype=float[8]):
irow := Vector[row](22,[1,1,2,2,2,3,3,4,4,4,4],datatype=integer[kernelopts('wordsize')/8]):
icol := Vector[row...

Hi,

I'm teaching numerical analysis with Maple and then I started with fixed iteration method.

When I programed the method which is simple, I got the solution as:

restart:with(Student[NumericalAnalysis]):

f := x->2*tan(x)-x-1;

g := x->arctan((1/2)*x+1/2);   # fixed point method where the solution of x=g(x) is the the solution f(x)=0

x[0] := 0.2; for k from 0 to 20 do x[k+1] := evalf(g(x[k])) end do; this line give the solution
