@Carl Love Thanks you! Your code seems work fine!

## thanks...

@vv Can you attach the Maple 2015 file, please?

Thanks.

## error...

@vv Sorry, the code returns me the error

Error, invalid proc termination

I reiterate my gratitude for your help.

I have coded this GKLS.mw  to compute the centers (I think that the calculus of the radii is easy).

However, CreaParam(2, 15, .6)

Return me 2 centers instead of 15. Can you help me please?

## thanks...

Sorry, but I do not understand yuor code at all. The radius R1 has to be equal to 0.6, and the center X1 not necessarily be the (0,0).

Also, your code return me an error:

Error, invalid sequence

(for r in R do   do v:=Xrnd(r) until check(v,r); S(++NS) := [v, r]; od)

## thanks...

Many thanks for your answer, but it is seems that PHCPack is not free: http://homepages.math.uic.edu/~jan/PHCpack/node11.html#SECTION000110000000000000000

## thanks...

Thank you very much. I feel that I do not defined well the Bernstein polynomials. Your definiton works!

## @acer  First at all, thanks for yo...

First at all, thanks for your reply. Yes, I have plotted correctly the Schubert function and the graph is as in the link https://www.sfu.ca/~ssurjano/shubert.html

My question is related to the plot the approximation by Bernstein polynomials (detailed in the cited paper in my post) of such function. That is, plot the function (x,y,p(x,y)), p(x,y) being the Berstein polynomial of f(x,y).

Maybe I have not defined this polynomial well, because the graph does not look like the Schubert function   plots.pdf

Again, thanks.

@acer Thanks!

## RealRange...

/   1\           /1   \
RealRange|0, -|, RealRange|-, 1|
\   7/           \3   /
/         /   1\           /1   \\
`union`|RealRange|0, -|, RealRange|-, 1||
\         \   7/           \3   //

but I really need to get [0,1/7], [1/3,1]. Can you help me with this, please?

Again, thanks
