Assuming that your lib file is located in a file at C:\MyDocs\MyMaple and named Mylib, do this: libname := "C:\\MyDocs\\MyMaple\\Mylib" , libname; with(Mylib); Or, the linux version, if that's your OS. Please see ?repository,management. Hope this helps, J. Tarr

If you want people to help you, please upload your worksheet to this site. J. Tarr

It's not clear what you are trying to do. Part of your problem may be that you are trying to use a Maple command "op" as a name. If so, just alter it in your worksheet to read Op. Otherwise, please upload your worksheet so that people here can try to help you. J. Tarr

Please see ?Statistics[Histogram] and ?stats[statplots, histogram]. You will find examples there of what you want. Hope this helps, J. Tarr

Try this: restart; t := 272*c^3-213*c^2+52*c-4; solve( t<= 10,c); fsolve(t); plot(t,c=0..10); plot(t,c= 0..0.5); Hope this helps J. Tarr

If I remember correctly, 2D input was introduced in Maple 6 and the idea was that it would help beginners to learn Maple 1D input and syntax. Document mode appeared in Maple 10 - some would say as a sales gimmick. In my opinion, document mode and 2D input in worksheet mode make for slow work. Once one has got the hang of Maple input, and it's not very hard, 1D worksheet mode is much faster. For those who are going to do serious work, using a text editor is essential and you need to know 1D Maple input for that. So, the advice has to be, get used to using Maple in 1D worksheet mode as soon as you can. Hope this helps you make your choice. J. Tarr

In Maple 10, pointplot can handle 2 column Matrices, and it would be a shame if that has been lost in Maple 11. Both of the following work fine in Maple 10, and I would be interested to learn if they work in Maple 11. restart; with(LinearAlgebra): Data := RandomMatrix(500,2,generator=rand(60..150)/10): st := time(): P2 := plots[pointplot](Data,symbol=cross): P1 := plot(x/2+2*x^(1/2),x=6..15): plots[display]([P1,P2],view=[5..13,4..15]); time()-st; Data := RandomMatrix(500,2,generator=rand(60..150)/10): LL := convert(Data,listlist): st := time(): P2 := plots[pointplot](LL,symbol=cross): P1 := plot(x/2+2*x^(1/2),x=6..15): plots[display]([P1,P2],view=[5..13,4..15]); time()-st; Hope this answers your second point. From the speed point of view, the second method *seems* faster. Hope this helps, J. Tarr

You could use the view option in pointplot or plots[display] - see ?plot,options. Using Maple 10, I couldn't reproduce your problem, so it looks as though one of the many improvements to 2D plots in Maple 11 is causing the problem. Hope this helps, J. Tarr

Are you looking for something like this? restart; with(LinearAlgebra): vectorC:=Matrix(1,4,symbol=c); vectorE:=Matrix([[e[0]],[e[1]],[e[2]],[e[3]]]); eq3:=evalm(vectorC&*vectorE); Map(solve,eq3,convert(vectorE,list)); Hope this helps, J. Tarr

In my experience, Zavan Karian's Statistics Supplement is more useful for applied statistics and easier to work with than Maple's packages. Hope this helps, J. Tarr

Stacey, I agree with Jacques C, document mode is best avoided - if you have to use it, please upload your worksheet and follow the instructions to copy and paste the part for which you need help. I believe the answer to your question in 1D Maple input is something like this: y := piecewise(x<2,x^2-5, x>2 and x<5,-3*x-7, x>5,abs(x-2) ); If you want to use document mode, or 2D Maple input, you need to copy and paste from the palette and then locate your cursor in the piecewise symbols and, as you said, do ctrl+shift+R. Hope this helps, J. Tarr

Stacey, Please see ?plot. You could do something like this: restart; plot((x^2-1)/(x-1),x=-5..5); Like others here, I am always very willing to help Maple newbies, but I don't do people's homework for them. That wouldn't be fair to their classmates, would it? J. Tarr

Please see ?plots[implicitplot]. You could do something like this: restart; plots[implicitplot](3*x^2 + 2*x*y + y^2 - 4,x=-5..5,y=-5..5); Hope this helps, J. Tarr
