I need to test a list of numbers to find if any of them are complex. if a complex is found then remove that complete row from the list. the potential complex numbers in my list are a, b and c. b is complex i.e has a non zero imaginery part in row 1 so only row 1 should get deleted. the a b and c were originally generated from the arcsin function. Would appreciate help on this. I know it should be simple enough to do. Thanks in advance.

I'm using the 64-bit version of Maple 16.0 and Excel 2010 (32-bit). (Most people using Office 2010 install the 32-bit version on 64-bit operating systems.)

Is it possible to use the Maple addin with the above setup ? I tried selecting WMIMPLEX64.xla, but Excel appears to want WMIMPLEX.xla (from the 32-bit).

What is the easiest fix ? Can I find a copy of WMIMPLEX.xla and use with with Maple64bit and Excel32bit ? Do I need to uninstall Maple64-bit and install Maple32-bit ?

Hello to everyone

Pls help,urgent....

I need to draw the deformation of one story building (for simplicity, 4 columns and 2 floors) whose columns and floors  under influence of external load acting to the left of the building at its intersection point undergo the deform shape like S . So means that when the building moves to the right its intersection point of column and floor has some small rotation.

Suppose a Record is created as follows in Maple.

> r := Record( foo = [ ... ], bar = Record( ... ), ... );

If this is saved with save() command to a text file, a new line is automatically inserted at every fixed character length, and it is very hard to read. I want the Record to be stored to a text file in more human readable way. Is there any good way to do that easily?

I have a column vector of lists. FWIW, it was generated by numerically solving an ODE and then map-ping the solution over a vector with values for the independent variable, like "yt:=map(solnn,xv)" where xv is a column vector with floats and solnn is the result of a dsolve(...,numeric). Each element of the solution vector yt has the form [t=..., y(t)=..., d/dt(y(t))=...] and has the type List.

I want to extract the solutions for y(t) (i.e. the numbers only) into a new...

i am modeling a simple standing wave. i have created three plots y1, y2 and y and then i am using animate to move them. the problem is that i cant add a legend describing every plot and i am not getting how to do this.

in addition when i click on the plot and then go to the legend menu, both show legend and edit legend are disabled.

here is my code

with(plots): y1:=0.01*sin(Pi/2*x-40*Pi*t);

                 y1 := -0.01 sin(-1/2 Pi x + 40 Pi t)

I'm very new to maple and i want to use DEplot to plot phase portraits.  how do i do this? I am using maple classic.

When maple does gauss elimination for matrice(student linalg). In "edit matrice" can i solve for x1,x2,x3..?

Hi there,

I am trying to find an analytical solution to an integral. Unfortunately, I only get the function call returned. Is there anything I can do to get Maple to solve it?

Thank you

Hi! I have 4 function. I wanna plot two of them in x=-0.5..0 range; the other two in x=0..0.5 range. How can I display that four function in one plot? Thanks!

kernel says it cannot interpret file.

Is there a limit in the input file dimension ?
