I have the following terms: >

a := .178131; 0.178131 >

e := -0.6814e-1*`if`(t = 0, 6, `if`(t = 1, 10, `if`(t = 2, 15, `if`(t = 3, 20, NULL))));

 f := 0.16242e-1*`if`(t = 0, 6, `if`(t = 1, 10, `if`(t = 2, 15, `if`(t = 3, 20, NULL))))^1.5;

The ODE is:

Q1: Write a procedure named MULTIPLYMATRIX to find the product of an n x m matrix by an
m x q matrix. Your procedure should print the result matrix. The dimensions n, m, q should be
input parameters in your procedure. Test your procedure by demonstrating multiplication of a 2 x
3 with a 3 x 4 matrix of your choice

 

I have been struggling to solve this problem.

I want to minimize this function for w, x and y:

((w^2)/2)+((a/3)*x^3)+(2by)+((2a/3)*y^3)

Subject to w+x+2y=1

Where a and b are positive constants

And also, I want to minimize this function for w, x, y and z:

((3w^2)/2)+((2a/3)*x^3)+(by)+(ay^3)+(bz)+((a/2)*z^3)

where a and b are positive constants.

I've tried a ton of stuff on maple and have been unable to figure it out.  Any help is greatly appreciated!

I have a multivariable function, F(n, g(1,0),g(0,1),g(0,2),g(1,1),g(2,1),...,g(n,1),g(n-1,2),...,g(1,n)), of indeterminates g(i,j) (omitting g(0,0) - in other words - let L = set of all pairs of nonnegative integers, (i,j), which satsify 1<= i+j <=n) of the following form F = product over all the (i,j) in L of g(i,j)^h(i,j) / ((i!

Hi

Does anyone know how to shade the tails (eg the lower and upper 5%) of a probability density function?

thanks!

I need to integrate an ODE : I use dsolve.

As there is not an exact solution, I use numeric integration :

F := y''(x) + a(x)*y'(x) + b(x)*y(x) ;

EDF := {F = 0, y(t0) = y0, y'(t0) = dy0};

Snum := dsolve(EDF, y(x), type = numeric);

S  := x --> rhs(Snum(x)[2]) ;

I can now plot the graph of the solution S.

But suppose I need also the graph of the derivative S'.
As this function is solution of Y' + a*Y + b*S = 0,
I code

I have a large number of lists labelled L1, L2, L3 ...etc.

I want to determine the number of elements in each list.  If I had labelled my lists L(1), L(2), L(3) ... I would easily have been able to pull out the number of elements with sequence

seq(nops(L(i)),i=1..3);

nops doesn't allow multiple arguments.  Is there any way I can use seq on the lists L1, L2, L3, ... etc  In other words, how can I have a two letter variable and get maple to vary the 2nd variable?

hi, i have a set of roots, say [a,b,c,d]. how do i make them so that maple will give me the roots like this:  {m=a},{m=b},{m=c},{m=d} ?

 

thanks

I have already plotted the intersection of 5 surfaces but need to plot their intersections, is this possible and if so how? Cheers

Dear All,

i am first time using maple for my cryptographic scheme i recently developed. I am wondering if there is any builtin package or library for AES Encryption/Decryption and SHA256 in MAPLE 11.

the "StringTools" can provide md5 hash of the message but i need SHA256 implementation and AES 256 bit encryption/decryption module in Maple.

any suggestions?

 

I was wondering if there is a way to compute the discriminant of a rank r quadratic form in maple? Alternatively, is there a way to diagonalize, via symmetric row and col operations, a symmetric matrix A over Z_p? For instance, modifying RowReduce in LinearAlgebra[Modular]. If I can do this then I can obtain the discriminant. Example: >with(LinearAlgebra[Modular]): >p:=5; >Matrix(4,4,[[0, 1, 1, 4], [1, 0, 1, 0], [1, 1, 0, 1], [4, 0, 1, 0]]); >RowReduce(p,A,4,4,0,0,0,0,0,0,0); # would like a symmetric row and column reduction

Hello.I could use some help to solve the folowing system, please.

Basically I have the 4 unknowns (A,P,C2,alfa)and I want to know their values by changing values to "a2" (eg. varying a2 from [0;80]).

With another software I solved matricially the EQ2;EQ3 and EQ4 for P,A and C2 with different values of a2 and then I replaced the P,C2 solutions (for each a2 value) on the EQ1 and tooked the value of "alfa" for each corresponding "a2". At the final I had the 4 unknows solved varying the "a2" value.
