I noticed that this function is used only for a discontinous function. What can I do if I have a discontinous data?

## From Matrix DE solution to Equation form...

Hey all I would like to know if after solving a Matrix Differntial Equation (general form, no initial conditions) there is a way to convert the solution matrix to equation form (i.e. y(t)= C_1e^(3t)+C_2e^(-t)+... etc). see yas david

## How to check the consistency of a system of equati...

I am working on a Maximum Likelihood problem and would like to know whether the LinearAlgebra package can be helpful. Up to now I have been using Maple only to check my work. However, someone pointed out that Maple's capabilities reach much further: it also can determine whether the system of equations is consistent and, if so, Maple can solve the equations. Unfortunately, I am only trained as a psychologist and I am still at the beginning of learning Maple's capabilities. Here are the three equations: f = (Y'b - 1t'b)(b'b)^-1 equation#1

## Arrays of equations and the Numeric BVP Solver...

Hello, I'd like to use the BVP solver to find the numeric solution to a large set of differential equations. The thing is, I have about 60 equations differing only by constants in the derivitave. Instead of typing in a set 60 equations with different constants, is there an easy way I can create an array of equations and use it with dsolve? Thanks!

## nothing but help...

I've got a promblem now. My teacher wants me to write a normalized programme with maple, yet I do not know how. I would like to know where can I find a normalized programme with standard format. If anyone who are familar with this subject, I am glad to accept your suggestions. Thanks very much:)

## background curve...

How do i find a background curve to a graph, i have data fitted with a spline and i need to find the background curve

## Predicate Logic Expressions...

Can Maple 10 be used to determine if the universal or existential closure of predicate logic sentences that may or may not contain quantifiers is valid ? For example, does the tautology, equivalent and other functions of the Logic package only apply to propositional sentences ? dc

## How much flexibility is there in v10 to format pag...

I am new to Maple 10, but have used other products for years. I tried v10 because the Maple website indicated that there was a great deal of flexibility in formatting pages. It seems to me, after a few days experimenting, that I cannot do more than put every thing in the middle of the page. Is this true? If not, is there a demo v10 sheet w/ instructions that shows how to do this? I can attach a pdf file of what I am interested in from Mathcad. Thanks much, Rich

## Stackmatrix precision by columns..??...

Can I display floating point numbers with a precision for inidivualy columns in a (for example) 3-column data table? How? Reply by email if you can...

## OpenMaple UI Access...

Hello, I am working on a program that creates symbolic algebraic expressions. I'd like to be able to "export" these to Maple. Ideally I'd like to have a menu option "Send to Maple" that would either start Maple or find an existing running version. It would then simply paste the expression in Maple syntax into the open UI. The OpenMaple API seems to only give access to the kernel which appears (and rightly so) to know nothing of the UI. Is this the case? Is there any API that would allow me to paste to an open Maple window? I tried enumerating all open Windows via MS Windows API functions. But since the Maple UI is Java based I couldn't get a pointer to the window...plus this seemed to be a pretty hacky solution to me.

## Help...

I have been trying to understand the example examples/Optimization LSSolve section (at the bottom) and use it for different data and a different equation, i only want to find residues for omega_o, F, m and b not omega in the equation F/sqrt(m^2*(omega^2-omega_0^2)^2+b^2*omega^2) How do i just find residuals for these four unknowns only. Thanks
