Hello all, I want to turn the following piece of code into a function of sorts by wrapping it in a proc. When I attempt to do so exactly as given in the below sample, 2 error messages are returned: The first is an 'Error, unterminated procedure' and the second 'Error, unable to parse'. > restart; with(LinearAlgebra); > func:=proc(params,a,b) eta_f:=params[1]: eta_s:=params[2]: eta_w:=params[3]: eta_int:=params[4]: omega:=params[5]: G:= params[6]: u[0]:= params[7]: params[7]: n:=a+b: Arand:=RandomMatrix(n,n):A:= Arand-Arand: end proc; To state my problem in it's completeness; For simplicity I have only included an excerpt of my full input - which runs fine before the introduction of 'proc' - but I encounter identical problems to that outlined above throughout. As such I assume a solution to the above excerpt can be applied generally.
I want to evaluate the limit as sigma=0 of the integral from -infinity to +infinity of V(t)*f(t) where f(.) is the normal density. I think that I must obtain V(mu) but I only get: "lim sigma->inf of integral etc etc. " The "commands" that I did use are: restart; > MyFunc1:=(t,sigma,mu)->int(V(t)*1/2*2^(1/2)/Pi^(1/2)/sigma*exp(-1/2*(t-mu)^2/sigma^2), t=-infinity..+infinity); >limit(MyFunc1(t,sigma, mu), sigma=0); Probably I am doing something wrong, because I am almost sure that MAPLE can do it. Could somebody please point my mistake or suggest any hint? Thanks a lot. JV
int((4*x-3)^3, dx) Tried to use Maple straight away to integrate the above. As it turned ou the answer was wrong.Does this mean that I have to solve it by way of substition Curious
Hi everyone, First things first, I really enjoy reading this forum and have found it quite helpful; kudos to the experts who make this a very valuable resource. That being said I've been using MAPLE 10 since its release and recently began working in the Worksheet mode rather than the Document mode - the benefits of which have been mentioned in previous topics and explains my shift. This has lead me to a problem which makes no sense to me and I could use a little help on. Essentially I have a list of values acquired from a strain gage signal (non-integer floats) and wish to select a value within the list closest to 10,000, retrieve the associated index for it and create a new list up to that value for further calculations. Here is the input (SG1 is my list):
I uploaded a code intended to create a step by step solution to find the area of a triangle, starting with the formula, substitution, and evaluation of that statement. However the value of b[3], the evaluation part, is placed infront of the statement instead of the last statement. I have been looking at the code for weeks but I get no where. Maybe a second eye will see what is wrong with the code. View on MapleNet or Download

What is the command which returns the length of a list? i.e. length of [1,2,3] is 3 ? More importantly, please tell me where in the help menu this command is listed. Thank you.
Hello! I have the following PDE: PDE := { diff(alpha[1](u, v), u) = -I*exp(I*u)*beta[1](u, v), diff(alpha[1](u, v), v) = -I*exp(-I*v)*beta[2](u, v), diff(alpha[2](u, v), u) = I*exp(-I*u)*beta[2](u, v), diff(alpha[2](u, v), v) = -I*exp(I*v)*beta[1](u, v), diff(beta[1](u, v), u) = (1/8*(I*exp(-I*v)*alpha[2](u, v)+(2*I)*beta[1](u, v)+(2*I)*exp(-I*(v+u))*beta[2](u, v)))*(a-1)-(1/8*(-I*exp(-I*u)*alpha[1](u, v)-(2*I)*beta[1](u, v)+(2*I)*exp(-I*(v+u))*beta[2](u, v)))*b, diff(beta[1](u, v), v) = (1/8*(I*exp(-I*u)*alpha[1](u, v)+(2*I)*beta[1](u, v)-(2*I)*exp(-I*(v+u))*beta[2](u, v)))*(a-1)-(1/8*(I*exp(-I*v)*alpha[2](u, v)+(2*I)*beta[1](u, v)+(2*I)*exp(-I*(v+u))*beta[2](u, v)))*b,
How do I, with Maple, differentiate the following y = (x- 1)^2/x Curious
Hi I wish to thank all those who generously helped me with my last prob. Now I have another. These are mainly related to the use of Maple with the application in question. How do I use Maple to differentiate the following: A=pi.r^2. I am not doing homework. I can do it without MAPLE. However I want to master Maple. Never used it before. The answer I get with Maple is different to the one I get myself: 2pi.r Curious Please replace this text with the link to your file. The link can be found in the File Manager
How do I format a variable with the superscript bar over the variable?

It's magic. The LEGEND() call is present in the PLOT structure, but it doesn't get displayed.


Hi, I'm trying to do a piechart. the following code generates one alright but I have no idea how I can make the labels be outside instead of inside the piechart. any ideas?? with(Statistics); PieChart([England = 341, Spain = 237, Germany = 93, France = 91, Unknown = 56, Wales = 40, Ireland = 39, Sweden = 35, Russia = 31, Other = 244], color = orange .. green); thanks Antje
Does anyone know a way to get Maple to take advantage of the type of matrix you are giving it? I have a block toeplitz matrix and am using Maple to find the eigenvalues and eigenvectors. Thanks in advance :D
I am trying to plot an equation containing special functions - namely, elliptic integrals. The goal is to plot equation (16) of the attached file. Any suggestions/guidance is appreciated. View on MapleNet or Download

I was wondering if Maple can read an inputfile the way tecplot can, or at least plot a huge list of coordinates WITHOUT using the pointplot command (it will take me to long to put all of my coordinates in pointplot's correct input format). I have a list of about 5000 coordinates (x and y) and I want to see y vs x in a 2D graph. Any help is GREATLY appreciated Thanks.
