I have this circuit to be simulated in Pspice. I'm a complete newbie to it. But so far have managed to make the schematic (adding external components, which were not available already in the library).
I have added models for AD8336, AD736 and AD8551 externally (models for which were available on Analaog devices website). Now when I try to run my simulation, I get errors as to the sub circuits used by AD8336 and AD736 are undefined (although I have added the libraries for these components to my design in the simulation profile).
P.S: I wanted to include the .cir file (model file) for AD8336 and AD736 here in for your reference as well as the list of errors that I get in my system log on running the simulation. But I'm unable to do so here. How do I share that so that I'm able to be more specific?

I have a Ceph cluster running with 18 X 600GB OSDs. There are three pools (size:3, pg_num:64) with an image size of 200GB on each, and there are 6 servers connected to these images via iSCSI and storing about 20 VMs on them. Here is the output of "ceph df":

Based on this, I expect about 1.7 TB RAW capacity usage, BUT it is currently about 9TBs!
RAW STORAGE:
CLASS SIZE AVAIL USED RAW USED %RAW USED
hdd 9.8 TiB 870 GiB 9.0 TiB 9.0 TiB 91.35
TOTAL 9.8 TiB 870 GiB 9.0 TiB 9.0 TiB 91.35
And the cluster is down because there is very few capacity remained. I wonder what makes this and how can I get it fixed.
Your help is much appreciated
The problem was mounting the iSCSI target without discard option.
Since I am using RedHat Virtualization, I just modified all storage domains created on top of Ceph, and enabled "discard" on them1. Just after a few hours, about 1 TB of storage released. Now it is about 12 hours passed and 5 TB of storage is released.
Thanks
Ive been looking at implementing GLCM within MATLAB using graycomatrix. There are two arguments that I have discovered (NumLevels and GrayLimits) but in in my research and implementation they seem to achieve the same result.
GrayLimits specified bins between a range set [low high], causing a restricted set of gray levels.
NumLevels declares the number of gray levels in an image.
Could someone please explain the difference between these two arguments, as I don't understand why there would be two arguments that achieve the same result.
From the documentation:
'GrayLimits': Range used scaling input image into gray levels, specified as a two-element vector [low high]. If N is the number of gray levels (see parameter 'NumLevels') to use for scaling, the range [low high] is divided into N equal width bins and values in a bin get mapped to a single gray level.
'NumLevels': Number of gray levels, specified as an integer.
Thus the first parameter sets the input gray level range to be used (defaults to the min and max values in the image), and the second parameter sets the number of unique gray levels considered (and thus the size of the output matrix, defaults to 8, or 2 for binary images).
For example:
>> graycomatrix(img,'NumLevels',8,'GrayLimits',[0,255])
ans =
17687 1587 81 31 7 0 0 0
1498 7347 1566 399 105 8 0 0

As you can see, these parameters modify the output in different ways:
In the first case above, the range [0,255] was mapped to columns/rows 1-8, putting 32 different input grey values into each.
In the second case, the smaller range [0,127] was mapped to 8 indices, putting 16 different input grey values into each, and putting the remaining grey values 128-255 into the 8th index.
In the third case, the range [0,255] was mapped to 4 indices, putting 64 different input grey values into each.
EDIT: To help clarify my question, I'm looking to get a fit to the following data:
I can get a fit using the cftool function, but using a least squares approach doesn't make sense with my binary data. Just to illustrate...
So, my goal is to fit this data using the fmincon function.
ORIGINAL POST:
I have data from a movement control experiment in which participants were timed while they performed a task, and given a score (failure or success) based on their performance. As you might expect, we assume participants will make less errors as they have more time to perform the task.
I'm trying to fit a function to this data using fmincon, but get the error "Error using fmincon (line 609)
Supplied objective function must return a scalar value."
I don't understand a) what this means, or b) how I can fix it.
I provide some sample data and code below. Any help greatly appreciated.

%Code:
% initial parameters - a corresponds to params(1), b corresponds to params(2)
a = 3.0;
b = -0.01;
LL = #(params) 1/1+params(1)*(log(time).^params(2));
LL([a b]);
pOpt = fmincon(LL,[a b],[],[]);
The mistakes comes from the function LL, that returns a number of values equal to the length of time.
To properly use fmincon, you need to have a function that returns only one value.
I believe logistic regression would fit your data and purposes nicely. In that case, why not simply use Matlab's built-in function for multinomial logistic regression?
B = mnrfit(time,error)
Regarding your function LL, are you sure you have entered the function correctly and are not missing a parentheses?
LL = #(params) 1/(1+params(1)*(log(time).^params(2)));
Without the parentheses, you function is equivalent to 1 + a*log(x)^b
I can't understand, where my ceph raw space is gone.

Raw usage is 4x real usage. As I understand, it must be 2x ?
Yes, it must be 2x. I don't really shure, that the real raw usage is 7.9T. Why do you check this value on mapped disk?
This are my pools:

total avail 34474223648
total space 132763577328
You can see, that the total amount of used space is 3 times more than the used space in the pool rbdkvm_sata (+-).
ceph -s shows the same result too:
pgmap v11303091: 5376 pgs, 3 pools, 31220 GB data, 7809 kobjects
93736 GB used, 32876 GB / 123 TB avail
I don't think you have just one rbd image. The result of "ceph osd lspools" indicated that you had 3 pools and one of pools had name "metadata".(Maybe you were using cephfs). /dev/rbd0 was appeared because you mapped the image but you could have other images also. To list the images you can use "rbd list -p ". You can see the image info with "rbd info -p "
i have an installation on memcache which i want to use in my production environment but when i have ran a couple of tests it seems that memcache doesn't free up memory even after it has used up all of it allocated memory, Also i logged in and ran a flush_all command but the objects are still in the cache.
Here are outputs from some tests

-m tells memcached how much RAM to use for item storage (in megabytes). Note
carefully that this isn't a global
memory limit, so memcached will use a
few % more memory than you tell it to.
Set this to safe values. Setting it to
less than 48 megabytes does not work
properly in 1.4.x and earlier. It will
still use the memory.
