When exporting plots some labels are occasionally cropped. This is true when exporting via the context menu or with plotsetup('gif', etc.) for instance (plotsetup also drops the third label in 3D plots, the context menu keeps it).

I discovered that scaling the plot from the context menu can help: is there a programmatic way to control the plot scale?

From the context menu: Manipulator -> Scale, the plot can be rescaled to ensure that all...

Hello,

i want to solve the following for q[b], theta is a symbolic coefficient. When I use the solve command it produces a RootOf that i cannot handle by using either allvalues or evalf. I can't use fsolve since there is theta 

In the previous question, we discussed a workaround for evaluating a multi-variable integration. 

For the following example 

> g := (e1, e2, e3) -> piecewise(e1+1.200000000 <= e2 and e3-2.400000000 <= e1, evalf(64.00000000*exp((-1)*8.000000000*e1^2)*exp((-1)*8.000000000*e2^2)*exp((-1)*8.000000000*e3^2)/Pi^2), 0);
> 
> evalf(Int((x, y, z) -> g(x, y, z), [-2 .. 2, -2 .. 2, -2 .. 2]), 3);

Maple could start execution and do the computation.

When an integration is successfully evaluated numerically, a float number is returned, otherwise the unevaluated expression is returned. I'm wondering whether Maple has a utility function which simply takes in whatever the integration evaluation gives and return a boolean flag indicating whether it is unevaluated or is a floating point result? 

Hi, I got a problem that "Warning, solutions may have been lost" when I solve 

eqns := {a+r*t*ln(l)+(1-l)^2*m-b-r*t*ln(s)-(1-s)^2*n = 0, a+r*t*ln(1-l)+l^2*m-b-r*t*ln(1-s)-s^2*n = 0}

vars := {l, s}

solve(eqns, vars)

Why?

hi

i write the followinf code in maple

eq1:= f'''(x) - f'(x)

is this posible in maple that i worte the above command like this

Linear:= d3/d(x) - d/d(x)

eq1:= linear (f)

thanks for youe attention in advance

hi

i have 2 equation named eq1 and eq2 with 2 unknown parameter a and b which each equation dependent to a and b. i want to achieve critical a and b to minimize eq1 and eq2.

previously i have eq1 and one parameter a only and i use the NLPSOLVE command. but , for above mention problem i dont know how achieve a and b?

thancks for your attenrion in advance

Question is very simple:

if I write square root as  f^(1/2) , then the compile function gives a error: 

Error, (in Print) rational numbers and arithmetic are not yet supported

if I write it as sqrt(f) then compile works.

But Maple seems to internally always convert sqrt(f) to f^(1/2). So, I am constantly getting the above error!

Is there a workaround? I have an impression of very poorly written Compile function....

any software help to see the Maple code inside the library with extension .lib?

So I have this array of plots with log vertical axes. I generate it with a seq(logplot(.....)) construct and then display the whole sequence. Works like a charm...except all plots have linear scale! So I try plot(...,axis[2]=[mode=log]): works fine for direct plot but not in display. I try to add the log axis to display, like display(...axis[2]=[mode=log]): same result, linear axes.

Is plots:-display unable to produce a log plot? I can obviously plot the log(data),...

acer discussed in a recent post the effect of different array types on performance.

I have, however, a much more elementary question: Maple has a bewildering number of differing data structures: Arrays, Vectors, lists, sets, tables,... Some of these are supersets of others.

Being still on the learning curve I am building a module with definitions of certain functions or procedures I use frequently, such as to make my life easier. A lot of my stuff uses array-like...

Hi, I have a set of data (see here:I-V_data.xls), voltage and current, which is measured from Keithley semiconductor analyzer, I want to load into Maple(version 15) and using formula as follow to fitting the curve, where I (i.e. current) appear at both right-hand-side and left-hand-side, V (i.e. voltage...

In geometry package, for example, i have the line d has equation 2*x + 3*y + 4 = 0. I want to choose an arbitrary point on the line d, how must i do? 

Hi there,

I would like to know if it is possible to get the results of a simulation as a table with the values of the output variable as numbers instead a graphic. for example:

time     temperature

0.1s     300k

0.2s     305K

.......

Thanks

Hello everyone. I'm a french student and I make a study on the double pendulum. I have written all of the equations into maple (6 equation for solid movement and 2 for point movement). We will work with 2 equations.

So i got my 2 differential equations (non linear) and I want to odeplot them and after plot the 2 solutions with plot.

Unfortunatly, after reading some post here and solutions, my problem still exist. When I odeplot my solutions : i have a warning message (so also when I plot) :
