Does anyone help which approach is good here.

you can do this:

Hi, I am creating a GUI which contains DropDowns. They are 10 dropdowns as you can see from the code. And I am using assignin to save each one of them into base workspace. But I would like to club all of them into a 2 char array's or 2 cell array's and send only two variables into the base workspace viz, Roll_nos and Projnames_GUI

Create two cell arrays and assign them in the base workspace:
roll_nos = {
app.StudentInfoDropDown.Value,
app.StudentInfoDropDown_2.Value,
app.StudentInfoDropDown_3.Value,
app.StudentInfoDropDown_4.Value,
app.StudentInfoDropDown_5.Value
};
projnames_gui = {
app.ProjectInfoDropDown.Value,
app.ProjectInfoDropDown_2.Value,
app.ProjectInfoDropDown_3.Value,
app.ProjectInfoDropDown_4.Value,
app.ProjectInfoDropDown_5.Value
};
assignin('base','Roll_nos',roll_nos)
assignin('base','Projnames_GUI',projnames_gui)

How can I search for a duplicate in a given string using a scriptlet?
ScripletInput= a,b,c,a
Here the letter 'a' is repeating. If it is repeating more than once, then it should exit, else it can go ahead.

Please see Remove occurrences of duplicate words in a string
The code below will remove duplicates in a string.
<script type="text/javascript">
str=prompt("Enter String::","");
arr=new Array();
arr=str.split(",");
unique=new Array();
for(i=0;i<arr.length;i++)
{
if((i==arr.indexOf(arr[i]))||(arr.indexOf(arr[i])==arr.lastIndexOf(arr[i])))
unique.push(arr[i]);
}
unique.join(",");
alert(unique);
</script>

I have this data of year, month, date. I want this to show as year,month,date in Matlab and don't know how to do.
X=(2014,01,02 2014,01,03 2014,01,07 2014,01,08 2014,01,09 2014,01,10 2014,01,13

The simplest way would be to reshape the matrix and use it accordingly. I demonstrate the way to reshape and print all the dates in US (MM/DD/YYYY) format.

X_in_better_format = reshape(X,3,42)';
for it = 1:size(X_in_better_format,1)
sprintf('The date is %d/%d/%d',X_in_better_format(it,2),X_in_better_format(it,3),X_in_better_format(it,1)) %US Format

I have a list of servernames
PARDC1 EURDC2 EURDC3 USADC1 USADC22 CHNDC1 CHNDC2
I have created a hashtable to pick the first 3 letters of servernames, and classify it in a region.
PAR = EMEA
EUR = EMEA
USA = NAM
CHN = APAC
I want to use the lookup table to classify all servers in appropriate regions.
How do I go about doing this in Powershell ?

You can create an empty hash table with
$hash = #{}
You can then add entries to it with
$hash['foo'] = $bar
or
$hash.foo = $bar
and access them the same way later again.
