Define a slightly messy function - in this case a sum of random Gaussians:

spikes:=sort([seq(RandomTools[Generate](distribution(Uniform(0,5))),i=1..300)]):
Spikes:=add(rand()/1e12*exp(-(Z-spikes[i])^2/2/.001^2)/(1+Z)^(5/2),i=1..nops(spikes)):

Takes no time at all to plot, or evaluate 10^3 times:

time(plot(Spikes,Z=0..5,numpoints=1000,adaptive=0));


Now put the whole thing in a procedure A(z), so that we can use A(z) as a function unless...

HEY EVERYONE,

HOW CAN I PROVE THE FOLLOWING BOTH ON PAPER AND USING MAPLE 13.

HAVING THE VECTOR A= (A1,A2,A3)

PROVE THAT

I'm doing some algebra with transfer functions, which are often written in LaPlace Transform notation, e.g. f(s) = 1/s.  One often wants to find the "gain and phase" of such, which is easy to do using the following steps:

1) Substitute "i omega" (imaginary unit, omega = frequency in radians) for s.

2) Express the complex quantity in polar (rho, phi) notation -- rho = amplitude, phi = argument (Phase).

So here's my question -- if I am developing...

Bonjour,

Hi, this is my first time here so hello! So im working on some questions my teacher gave to me in my class, and im having quite difficulty getting started on them, if anyone could help, that be great, thanks!

2. The first application of Newton’s method is to solve the equation

Hi,I explained my problems in the WS below,Thanks in advance.

Hi,

I have the eq. as shown below:

2*x^3+(2*K1*nbo4+3*K2*nbo4*PH2O)*x^2+3*K1*x*nbo4^2*K2*PH2O-3*K1*nbo4^2*Ti*K2*PH2O = 0

where x is the only variable, however I would like to solve this eq with respect to x for a list of 5 different values for the constant K1 (e.g. 1, 2, 3, 4, 5), and then get an output with the 5 numerical solutions to the eq.

I have tried to make the following matrix:

K1 := [1,2,3,4,5]

fsolve(2*x^3+(2*K1*nbo4+3*K2*nbo4*PH2O...

Hello. I am trying to plot a few lines in a threedimensional space in maple 14. The lines are doing what I want, bu they are all pretty ragged. Is there something like a smooth function?

Increasing the numpoints improves the situation, but my processingpower isn't big enough for satisfactory results.

Thanks a lot Ivo

I have some rather complicated equations which Maple couldn' solve analytically. So I plotted the intersect (which worked) and now I wanted to extract the data from the plot to use it in Origin. I managed to get the data with the op comand but somehow I can't use writedata to create a txt file.

In addition does anyone now how to get the length of the output array from intersectplot?

Is there a better way to get what I want?

Hello,

I have a parametric function which represent an angle and parameters are angles too.

theta=f(nu,phi)

I plot theta whith plot3d but when theta become inferior to -90°, maple draw a gap of 180°

How can I plot theta without gap ?

Thank's

Greetings All 
I can create/plot an egg shape waveform using the equation 
below:

 
y(x) = sqrt(abs[sin(x)+0.1sin(2x)]) 

Here's a link to it below/ image of it attached

I want to export a figure,

whatever the format I select, for example bmp,

I found that the resolution of that exported bmp file is fixed 400*400,

how can I change the resolution with a command,

because of its precise control,

help me,

thank you in advance.
