I have a vector that looks like this:"GOOG.NASDAQ_A.4""GOOG.NASDAQ_AAC.4""GOOG.NASDAQ_AACC.4"Now in order to make the api call it has to be expressed as:http://quandl.com/api/v1/multisets.csv?columns=GOOG.NASDAQ_A.4,GOOG.NASDAQ_AAC.4,GOOG.NASDAQ_AACC.4or as:"http://quandl.com/api/v1/multisets.csv?columns=GOOG.NASDAQ_A.4,GOOG.NASDAQ_AAC.4,GOOG.NASDAQ_AACC.4"How would I make that transformation? It looks simple but it is difficult ie string notation and you cant copy past (thousands of stocks). LL_101)_Quandl_Get_D.mw

Hello ...

how to convert matrix to single code like below

for example ,a:=

how i want to combine a like b:= 00000001111000111100000110011001110101010101

accroding to http://www.maplesoft.com/support/help/Maple/view.aspx?path=convert%2fVector set can't be converted to Vector.

So I have to convert set to list, then convert the list to a Vector:

a:={1,2}:convert(convert(a,list),Vector);I was wondering if there is a short way to type this or a command that I might have overlooked, as it seems too much typing for such a common operation. (it would be nice if convert would support this automatically by doing the above so one can just type convert(a,Vector). I am using Maple 17.02. I googled around, and did not find anything.

On a side note: The reason I ask, is that dsolve and many other operations like it, return the solutions as a set. Many times I need to multiply this by a Matrix. Hence the conversion need.

I have list for a:=[11110, 10101,100,10101], but, this list i want assume that all number is base 2..so, how i want to convert to base 10?

Hello....how to convert decimal to binary??for example [10, 3,90,6]..how to convert this number into binary??

i interpolate a function in some knots by BSplineCurve, the resulting function is parametric.

how i can convert this parametric function to a function?

thanks.

How can I copy and paste equations from Maple to Microsoft Word not in picture form so that I can edit.

I have some large equations derived in maple but want to paste them on Microsoft Word, where I am writing my paper.

Thanks

Hello all,

I have a question about converting a continuous piecewise function to Heaviside function, which the function includes trunc() in its conditions.

(I found differentiating piecewise function gives me "undefined" at boundary)

When I do that operation (convert(piecewisefunc, Heaviside)) I get the error below.

"Error, (in piecewise/simprootsstep) cannot determine if this expression is true or false: 0 < 183.3333333*Pi"

I want to use for do loop and the print statement. print(h, AA) gives two columns left for h and right for AA separeted by comma. How to change this two column presentation so that I can get the sequence of h and sequence of AA. Note that print(h) and print(AA) gives two separate columns. But I want to convert print(h, AA).

for h from 0.01 by .1 to 5 do AA := (1+h)/h^2; print(h, AA) end do:

One of those vexing things that should be easy:

I am reading in a data file using ImportMatrix. Since the file has one column with texual data I cannot use datatype=float since that bombs. I >can< ImportMatrix with datatype=string or anything.

I then extract columns using the appropriate command and want to do something numeric with them (only with those columns that have correct floating point numbers). That fails since my data are now not floats (even when using anything...

An intersection in my neighbourhood, currently controlled by a 2-way stop, is under consideration to become a 4-way stop. This means the traffic that currently has the right-of-way will be required to come to a complete stop, wheras previously they could have coasted down the hill, and accelerated up the other side. Politics aside, I was curious to explore the following question:

Hi again! :-)I just ran into another problem with units...I want to remove all units from an expression like this oneV[dis]:=(3/100000)*Unit('m')^3+0.1e-2*Pi*Unit('m')^2*(.112-0.28e-1*cos(theta)-sqrt(0.7e-2-0.1e-2*sin(theta)^2))I've tried with convert(V[dis],'units_free') but Maple wont let me use that command, when the expression contains units in powers (square and cubic).I guess there is another way arround, but how?Best regards

Hi,

with great interest and surprise I read the post"Converting Half-Angle Trig Formulas to Radicals".Isnt it possible to evaluate cos(arccos(13/14)/3) alsoto an exact expression in radicals ?I simply do not succeed with my humble knowledge ofthe Maple commands/internal workings...Would be great if someone finds a solution ( of an unsolvable problem ??? ).

Use RSA with the modulus n=119 and the exponent e=7, with the 95-character alphabet consisting of the printable ASCII characters to encrypt the word "Yes". Recall that the alphabet is given by

Alphabet:=cat(Select(IsPrintable,convert([seq(i,i=1..255)],bytes)));

so that Y=57, e=69, s=83. Give your encryption as a list of three numbers.

Is there any way to convert the output of ToInert to a graph/tree representation? ToInert's output type is a function and I've tried converting it to an expression first but didn’t succeed. I've also looked for functions in the GraphTheory package that could help in this process but didn’t manage to find anything useful.Thank you.
