Hi all
I am running a NVT simulation for some structure and want to draw the phase diagram for T vs V.
In my code I set some special value for temperature and also for volume. Also I have the analytic formula for my interaction potential.
But I don't know how I can draw the binodal line for...
thanks but I have mathematica 7 and when I type that code, it gives error that unknown plotlegends in contourplot ! however, I write : needs"plotlegends'" too.
how can I put "PlotLegends -> Automatic" in CountorPlot?
I search google but I couldn't find anything suitable for the above code ! Iwant mathematica to find plotlegend in an automatic way, not by writing for example 1 to -1
thanks
Dear friends
I plot a Contour plot from a function with mathematica, but I don't know how can I add a small box near my figure that explain which value refer to which color?
I put my code below, please help me with adding colordata to my code for having reference for colors.
t = 0.01...
polyfit
and if I want to fit my points with such a finction:
y=(x-a)^n + b
what should I type in polyfit?
I mean I have some x and y values but I find the relation between x and y in a way that I have a function like y=(x-a)^n + b
and then I want to find the exact value of a,b, n?
thanks
Dear users
I have some points with coordinate x and y
forexample :
x=[1 2 3 4]
and y=[2 4 6 8]
and then I want to fit these 4 pair of points with some function
for example
y=a*x+b
(here I know that the answer is a=2 and b=0)
what should I...
thanks but my function is very complex and in this way MATLAB cannot do anything.In fact it said that the integral cannot be calculated
How can I do the integral numerically but with 2 symbols?
I mean that integrate over x ,y,z with a numerical method but with 2 symbols of t and m .
thanks...
symbolic triple quad
I want to get 3variable integral from a function which is in terms of x,y,z,L,T
but I"T" and "L" are just symbols
and want to integrate over x ,y,z
How can I take triple integration from a symbolic function??
thanks alot
thanks for your guide
But it seems that you didnt understand what I meant.Let me tell you in another way
forget about that special 12*12 matrix or even 4*4 matrix
we have one matrix in terms of x,y,z, we want its eigenvalues and after finding them( which are still in terms of x,y,z) we want t...
my main matrix that is 12*12 is complex for MATLAB to find its eigenvalues.in above code I just wrote this 4*4 as an example for explaining my purpose.
matlab cannot find its eigenvalues in terms of x,y,z
No my matrix is defferent in size forexample 12*12 and…
but I now just write the 4*4 matrix that is simple and want to test code
I wrote a code and want to tell my purpose easier
This is all the thing that I want to dos=[ ] 4*4 matrix in terms of x,y,z
s1 , s2,s3,s4 are its eigenvalues
I...
theanks a lot but the thing that make my problem hard is that I don't have an explicit function in terms of x,y,z. My function will be made through those sums of integral.
see, I have one matrix that I must do set of algabric operation on its eigenvalues and after finding an expression in terms...
thanks a lot but sorry it has some errors that I don't know how to solve them
would you mind cheking your code?
and also what is the form of funhandle that I must write in function? forexample if I write :myTrap(x,[0,1],100) it takes errors.
thank you
dear users
I want to do a triple integration over x ,y ,z in MATLAB but because my expression under the integral is so complicated I want to change integrals to sum by Trapezoid method using a loop in MATLAB but for doing that I have 3 integrals and so 3 for loops for summing over x , y , z...
