Is there a way to remove the small dashed box that shows up while one is typing in document mode?
Also, is there a way to remove italic style from everything? I do not like italic at all. I tried many things, such as

Format > Styles. Select the 2D Input character style and click modify

but when I start new line, it goes back to italic.

I can also open the style sheet file (my_styles.mw) that I use, and look at the XML there. What do I need to change...

Hi folks, I'm running Maple 17.02 and getting very different behaviors from subs and isolate. My actual expressions are way more complicated but this simple example illustrates the problem:

restart; with(PDEtools); F := diff_table(f(x, y, w, z, a, b));

subs(F[x] = Z(x, y, w, z, a, b), F[x]+F[x, b]-10);

subs(F[x] = Z(x, y, w, z, a, b), F[x]+F[x, y]-10);

The last line gives me what I want  Z+Z[y]-10 but the second line gives me Z+F[x,b]-10....

I keep getting this error and have no idea how to fix it.

Error, (in Elements:-Maplet) `Elements:-ElementTable[typ]` does not evaluate to a module

This is my code for the section with the error. Any help would be greatly appreciated.

FindParamTan:=Maplet(onstartup = RunWindow(MAIN),
Window[MAIN](title="Computing Vertical and Horizontal Tangents to Parametric Curves",
[ [ halign=none,
    Button("New Curve", Evaluate(function = "ask"), background=magenta),

An elementary example of successful using Threads:

Hi,

tmp:=seq([phi[5-j]*(1-p[6-j]),phi[5-j]*p[6-j]],j=1..4);
Vector(8,[seq(op(tmp[i]),i=1..4)]);

"tmp" is basically what I want. Some kind of 'paired' terms, indexed in reverse order.

I wonder if there is a better (perhaps more efficient and "direct") way to do it?

Thanks,

casper

Hi all

 
i am solving a system of four coupled differential equations using bvp[midrich]approach..

The code i am using is in the attach files 

command is like

> A1 := dsolve({bc, eq1, eq2, eq3, eq4}, numeric, output = array([seq(0+0.5e-2*i, i = 0 .. 200*bb)]), method = bvp[midrich]);

with(plots)

 I have a system of 4 rational equations involving 6 variables. I want to solve this system for 4 variables. 

Whenver I try to do this I get either an error message about solutions being lost, or maple being unable to allocate enough memory.

The Commands involved are here: 

Hello,

I want to optimal control, i.e. determine command which minimize an onjective function.

So I want know how I can use the Maple function "optimization[NLPSolve]" in a custom block of Maplesim ?

(I do that in Matlab with "fminsearch" and a Matlab function block but I don't manage to do it with maplesim)

Hello,

I use Maple to solve dynamics of multibody systems. In the mechanical system i study, all my kinematic schemes use the parameter gamma and the project i work on, many people use the parameter gamma.

The issue is that i use the parameter gamma(t) depending of the time and if i use this parameter Maple treat this parameter as the Euler constant gamma and consequently make bad simplifications.

Is it possible to add a code lign to desactivate this...

An indefinite integral cancels out one differentiation:

int(diff(w(s),s,s),s)=diff(w(s),s);

But for a definite integral Maple does not recognize that:

int(diff(w(s),s,s),s=0..L) = int(diff(w(s),s,s),s=0..L);

What I would have expected is something like:

int(diff(w(s),s,s),s=0..L) = eval(diff(w(s),s),s=L)-eval(diff(w(s),s),s=0);

I cannot get Maple to recognize this even when assuming real or positive.

What I am really after is this: w(s...

Good morning sir,

I request you to support me How to generate the maple procedure for QR-Method in linear Algebra?

Good morning sir,
