I tried to download image from my server over www. In UnityPlayer it is all right, but when i run app on xcode it is crash.
I check log on server and there was no request from ios only from webplayer:

I am trying to reframe a polynomial equation using MATLAB. For example I have the following polynomial equation:
758622.2445*x2+-418477.9101*x2^2+27.50552059*x1-29.66792273*x1*x2+7.993937155*x1*x2^2-0.01387653551*x1^2+0.007688875184*x1^2*x2+-458420.9152*1+9.035554275e-08*x1^3+76949.5016*x2^3=y
I want to rewrite this equation to find x1 with respect to x2 and y. Is there a way in MATLAB that I can do this?
Regards,
Vivekram
You can do it with symbolic maths:
syms x1 x2 y
eq=758622.2445*x2+-418477.9101*x2^2+27.50552059*x1-29.66792273*x1*x2+7.993937155*x1*x2^2-0.01387653551*x1^2+0.007688875184*x1^2*x2+-458420.9152*1+9.035554275e-08*x1^3+76949.5016*x2^3-y; %note the "-y"
Then solve for x1:
answers=solve(eq,'x1');
This gives a somehow slightly impractical answer:

Hello I have to simplify the first expression which is from a 7 segment Display assignment.
upper case means it is a NOT so for example the first part ZYXW means NOT z AND NOT y AND NOT x AND NOT w. I hope that makes sense.
So the problem is i found the answer for the expression which simplifies to
a = z + x + yw + YW
however my simplification ends at a = zYX
bellow are the steps for my simplification, could someone identify the problem please.
a = ZYXW + ZYxW + ZYxw + ZyXw + ZyxW + Zyxw + zYXw + zYXW
a = ZYXW + ZYxW + ZYxw + ZyXw + ZyxW + Zyxw + zYX(w + W)
a = ZYXW + ZYxW + ZYxw + ZyXw + ZyxW + Zyxw + zYX(1)
a = ZYXW + ZYxW + ZYxw + ZyXw + ZyxW + Zyxw + zYX.1
a = ZYXW + ZYxW + ZYxw + ZyXw + ZyxW + Zyxw + zYX
a = ZYXW + ZYxW + ZYxw + ZyXw + Zyx(W + w) + zYX
a = ZYXW + ZYxW + ZYxw + ZyXw + Zyx(1) + zYX
a = ZYXW + ZYxW + ZYxw + ZyXw + Zyx.1 + zYX
a = ZYXW + ZYxW + ZYxw + ZyXw + Zyx + zYX
a = ZYW(X + x) + ZYxw + ZyXw + Zyx + zYX
a = ZYW(1) + ZYxw + ZyXw + Zyx + zYX
a = ZYW.1 + ZYxw + ZyXw + Zyx + zYX
a = ZYW + ZYxw + ZyXw + Zyx + zYX
a = ZYW + Zw(xY + Xy) + Zyx + zYX
a = ZYW + Zw(x.1 + X.1) + Zyx + zYX
a = ZYW + Zw(x + X) + Zyx + zYX
a = ZYW + Zw(1) + Zyx + zYX
a = ZYW + Zw.1 + Zyx + zYX
a = ZYW + Zw + Zyx + zYX
a = Z(YW + w + yz) + zYX
a = Z(Y.1 + yz) + zYX
a = Z(Y = yz) + zYX
a = Z(z) + zYX
a = Z + z + zYX
a = 1 + zYX
a = zYX
Hey I think this exercise is for using Karnaugh Maps. With those its quite simple. Just look here: Karnaugh Map Wiki
First you create a truth table, like the one at the start of this tutorial.
The 16 rows represent all combinations of your 4 variables. You get the result of a row, by comparing it to your function.
So 0 0 0 0 is equivalent to ZYXW and the solution would be 1 because ZYXW is in your function.
0 0 0 1 would be ZYXw which is not in your function, so the solution is 0.
0 0 1 0 would be ZYxW which is in your function, so the solution is 1.
Do this for all 16 rows. Then go ahead like in the
Tutorial.
I have been suffering to trace the crash I am getting on the actual device (iPhone/iPad) in my Universal App without being able to identify the cause of that crash. It is been couple months now and no progress has been done. I have attached the crash log from my iPhone. Please help I am getting depressed from this pain!

You need to symbolicate the crash report is pretty easy using Xcode organizer, you just need to drag into it (device tab). For more there is an Apple Tech Note.
After that we can understand better the crash.
In your XCode Debugger Console :
di -s 0x3a58197a
Execute the above command. You'll get the Class where your app crashed. If you don't get it here. Try to change the memory address with your following trace. Use one at a time in your XCode Debugger.

I'm trying to find the eigenvectors of a symbolic 3x3 rotation matrix in MATLAB, it appears to work for some inputs but not all, for example:
A =
[ cos(q), -sin(q), 0]
[ sin(q), cos(q), 0]
[ 0, 0, 1]
[V,lambda]=eig(A)
V =
[ 0, -i, i]
[ 0, 1, 1]
[ 1, 0, 0]
lambda =
[ 1, 0, 0]
[ 0, cos(q) - sin(q)*i, 0]
[ 0, 0, cos(q) + sin(q)*i]
this works fine, however if I try something which is not a rotation about a unit axis (x,y,z) I get the following error:
A =
[ cos(q), -sin(q), 0]
[ 0, 0, -1]
[ sin(q), cos(q), 0]
>> [V,lambda]=eig(A)

I'm using the eigenvalues to find the axis of rotation of the matrix, and I need to use it for much more complicated systems
Any help would be appreciated.

syms q
A = [cos(q) -sin(q) 0 ; 0 0 -1 ; sin(q) cos(q) 0]
[V,lambda] = eig(A)
I get the following (rather long) result:
A =
[ cos(q), -sin(q), 0]
[ 0, 0, -1]
[ sin(q), cos(q), 0]
V =

The problematic example you gave is not a general rotation matrix, 1 is not an eigenvalue. See more here http://en.wikipedia.org/wiki/Rotation_matrix. This shouldn't affect the matlab function however, you are guaranteed a basis of generalized eigenvectors over the complex numbers. Do you have any more information about the error? I'm noticing some calls to symmetric matrix-based functions, have you tried calling eig with the option 'qz' to explicitly call the non-symmetric based algorithm?
