Boolean Algebra Expression Simplification - boolean

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.

Why does my app keep crashing since iOS 13?

My problem is that my app has been crashing since iOS 13. The app doesn't work on any iPhone anymore. A bit strange, however, is that the iPhone simulators on iOS 13 all work fine. Here is the output of the lldb console after I type bt:

Does anyone have any idea how to fix the problem? I don't know where to start.

Using Cocoa NSSavePanel in Sandbox causes Assertion failure

I'm trying to use the NSSavePanel and added this line to my code.
let test = NSSavePanel()
Everytime this code is called the this error appears.
I'm not quite sure what is happening here because I'm only creating a new object.
Any help appreciated.
Thanks!

Your File Access permissions for the User Selected File type are probably still set to the default Read Only value
Navigate to the 'Capabilities' tab for your target
Set the User Selected File permission to Read/Write
Run your app (the bridge absent error should be gone)

Looking at the last column, if the last column is >= 5 then I want to count the lines till the column is greater than 5 until it falls back to < 5. Also the output I want should be like this for sample file
chr10 299945 299985 6
chr10 300185 300209 8
299945 comes from the 2nd column where the first 6 starts and 299985 comes from 3rd column where the last 6 ends. Similarly for 8.
I want to do this in Perl.
I tried writing the Perl script but cannot understand how to get coordinates properly.
#!/usr/bin/perl-w
use strict;
use warnings;
open F,'/user/tmp/output.bed',or die $!;
my $i=0;
while(<F>){
chomp;
my #s = split;
if($s[6] >= 5){
$i++;
}else{
if($s[6] < 5){
$i = 0;
}
}
}
How can I do it.
Thanks in advance
Regards

Use a range operator:
use strict;
use warnings;
my #last;
while (<DATA>) {
my #cols = split ' ';
if (my $range = $cols[-1] >= 5 .. $cols[-1] < 5 || eof) {
#last = #cols[0..2,-1] if $range == 1;
print "#last\n" if $range =~ /E/;
$last[2] = $cols[2];
}

Do you need that counting? Your output seems to not incorporate it...
Using your code sample:
#!/usr/bin/perl-w
use strict;
use warnings;
open F,'/user/tmp/output.bed',or die $!;
my $i=0;
my $wasTheLastGreaterThan5 = 0;
while(<F>){
chomp;
my #s = split;
if(($s[6] >= 5) && !$wasTheLastGreaterThan5){
# Switched from smaller to greater than 5, do something here.
$wasTheLastGreaterThan5 = 1;
}elsif(($s[6] < 5) && $wasTheLastGreaterThan5){
# switched from greater to smaller, do something here.
$wasTheLastGreaterThan5 = 0;
}
else {
# Did not switch, if you need to count, you could do so here.
}
}

Have got the same problem. Throwing UIAlert on main thread resolved the thing for me. But on ur log stack it seems that you are already one the main thread.

Symbolic Eigenvalues Matlab Error

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)
Warning: basis of eigenspace for eigenvalue cos(q)/3 - (cos(q)^2/3 + cos(q)^3/27 + sin(q)^2/2 + ((cos(q)/3 - cos(q)^2/9)^3 +

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.
Thanks

I am unable to reproduce the error (tested on MATLAB R2010b):
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:

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?
